- NAME
- AddFreeList - add memory to a free list.
-
- SYNOPSIS
- status = AddFreeList(free, mem, len)
- D0 A0 A1 A2
-
- BOOL AddFreeList(struct FreeList *, APTR, ULONG);
-
- FUNCTION
- This routine adds the specified memory to the free list.
- The free list will be extended (if required). If there
- is not enough memory to complete the call, a null is returned.
-
- Note that AddFreeList does NOT allocate the requested memory.
- It only records the memory in the free list.
-
- INPUTS
- free -- a pointer to a FreeList structure
- mem -- the base of the memory to be recorded
- len -- the length of the memory to be recorded
-
- RESULTS
- status -- TRUE if the call succeeded else FALSE;

- NAME
- BumpRevision - reformat a name for a second copy.
-
- SYNOPSIS
- result = BumpRevision(newbuf, oldname)
- D0 A0 A1
-
- char *BumpRevision(char *, char *);
-
- FUNCTION
- BumpRevision takes a name and turns it into a "copy_of_name".
- It knows how to deal with copies of copies. The routine
- will truncate the new name to the maximum dos name size
- (currently 30 characters).
-
- INPUTS
- newbuf - the new buffer that will receive the name
- (it must be at least 31 characters long).
- oldname - the original name
-
- RESULTS
- result - a pointer to newbuf
-
- EXAMPLE
- oldname newbuf
- ------- ------
- "foo" "copy_of_foo"
- "copy_of_foo" "copy_2_of_foo"
- "copy_2_of_foo" "copy_3_of_foo"

- NAME
- DeleteDiskObject - Delete a Workbench disk object from disk. (V37)
-
- SYNOPSIS
- result = DeleteDiskObject(name)
- D0 A0
-
- BOOL DeleteDiskObject(char *);
-
- FUNCTION
- This routine will try to delete a Workbench disk object from disk.
- The name parameter will have a ".info" postpended to it, and the
- info file of that name will be deleted. If the call fails,
- it will return zero. The reason for the failure may be obtained
- via IoErr().
-
- This call also updates the Workbench screen if needed.
-
- Using this routine protects you from any future changes to
- the way icons are stored within the system.
-
- INPUTS
- name -- name of the object (char *)
-
- RESULTS
- result -- TRUE if it worked, false if not.
-
- EXAMPLE
-
- error=NULL;
-
- *Check if you have the right library version*
-
- if (((struct Library *)IconBase)->lib_Version > 36)
- {
- if (!DeleteDiskObject(name)) error=IoErr();
- }
- else
- {
- * Delete name plus ".info" *
- }
-
- if (error)

-
- NAME
- FindToolType - find the value of a ToolType variable.
-
- SYNOPSIS
- value = FindToolType(toolTypeArray, typeName)
- D0 A0 A1
-
- char *FindToolType(char **, char *);
-
- FUNCTION
- This function searches a tool type array for a given entry,
- and returns a pointer to that entry. This is useful for
- finding standard tool type variables. The returned
- value is not a new copy of the string but is only
- a pointer to the part of the string after typeName.
-
- INPUTS
- toolTypeArray - an array of strings (char **).
- typeName - the name of the tooltype entry (char *).
-
- RESULTS
- value - a pointer to a string that is the value bound to typeName,
- or NULL if typeName is not in the toolTypeArray.
-
- EXAMPLE
- Assume the tool type array has two strings in it:
- "FILETYPE=text"
- "TEMPDIR=:t"
-
- FindToolType( toolTypeArray, "FILETYPE" ) returns "text"
- FindToolType( toolTypeArray, "filetype" ) returns "text"
- FindToolType( toolTypeArray, "TEMPDIR" ) returns ":t"
- FindToolType( toolTypeArray, "MAXSIZE" ) returns NULL

- NAME
- FreeDiskObject - free all memory in a Workbench disk object.
-
- SYNOPSIS
- FreeDiskObject(diskobj)
- A0
-
- void FreeDiskObject(struct DiskObject *);
-
- FUNCTION
- This routine frees all memory in a Workbench disk object, and the
- object itself. It is implemented via FreeFreeList().
-
- GetDiskObject() takes care of all the initialization required
- to set up the object's free list. This procedure may ONLY
- be called on a DiskObject allocated via GetDiskObject().
-
- INPUTS
- diskobj -- a pointer to a DiskObject structure

- NAME
- FreeFreeList - free all memory in a free list.
-
- SYNOPSIS
- FreeFreeList(free)
- A0
-
- void FreeFreeList(struct FreeList *);
-
- FUNCTION
- This routine frees all memory in a free list, and the
- free list itself. It is useful for easily getting
- rid of all memory in a series of structures. There is
- a free list in a Workbench object, and this contains
- all the memory associated with that object.
-
- A FreeList is a list of MemList structures. See the
- MemList and MemEntry documentation for more information.
-
- If the FreeList itself is in the free list, it must be
- in the first MemList in the FreeList.
-
- INPUTS
- free -- a pointer to a FreeList structure

-
- NAME
- GetDefDiskObject - read default wb disk object from disk. (V36)
-
- SYNOPSIS
- diskobj = GetDefDiskObject(def_type)
- D0 D0
-
- struct DiskObject *GetDefDiskObject(LONG);
-
- FUNCTION
- This routine reads in a default Workbench disk object from disk.
- The valid def_types can be found in workbench/workbench.h and
- currently include WBDISK thru WBGARBAGE. If the call fails,
- it will return zero. The reason for the failure may be obtained
- via IoErr().
-
- Using this routine protects you from any future changes to
- the way default icons are stored within the system.
-
- INPUTS
- def_type - default icon type (WBDISK thru WBKICK). Note that the
- define 'WBDEVICE' is not currently supported.
-
- RESULTS
- diskobj -- the default Workbench disk object in question
-

- NAME
- GetDiskObject - read in a Workbench disk object from disk.
-
- SYNOPSIS
- diskobj = GetDiskObject(name)
- D0 A0
-
- struct DiskObject *GetDiskObject(char *);
-
- FUNCTION
- This routine reads in a Workbench disk object in from disk. The
- name parameter will have a ".info" postpended to it, and the
- info file of that name will be read. If the call fails,
- it will return zero. The reason for the failure may be obtained
- via IoErr().
-
- Using this routine protects you from any future changes to
- the way icons are stored within the system.
-
- A FreeList structure is allocated just after the DiskObject
- structure; FreeDiskObject makes use of this to get rid of the
- memory that was allocated.
-
- INPUTS
- name -- name of the object (char *) or NULL if you just want a
- DiskObject structure allocated for you (useful when
- calling AddAppIcon in workbench.library).
-
- RESULTS
- diskobj -- the Workbench disk object in question

-
- NAME
- GetDiskObjectNew - read in a Workbench disk object from disk. (V36)
-
- SYNOPSIS
- diskobj = GetDiskObjectNew(name)
- D0 A0
-
- struct DiskObject *GetDiskObjectNew(char *);
-
- FUNCTION
- This routine reads in a Workbench disk object in from disk. The
- name parameter will have a ".info" postpended to it, and the
- info file of that name will be read. If the call fails,
- it will return zero. The reason for the failure may be obtained
- via IoErr().
-
- Using this routine protects you from any future changes to
- the way icons are stored within the system.
-
- A FreeList structure is allocated just after the DiskObject
- structure; FreeDiskObject makes use of this to get rid of the
- memory that was allocated.
-
- This call is functionally identical to GetDiskObject with one exception.
- If its call to GetDiskObject fails, this function calls GetDefDiskObject.
- This is useful when there is no .info file for the icon you are trying
- to get a disk object for. Applications that use workbench application
- windows MUST use this call if they want to handle the user dropping an
- icon (that doesn't have a .info file) on their window. The V2.0
- icon editor program is an example of a workbench application window
- that uses this call.
-
- INPUTS
- name -- name of the object (char *) or NULL if you just want a
- DiskObject structure allocated for you (useful when
- calling AddAppIcon in workbench.library).

- icon.library/MatchToolValue icon.library/MatchToolValue
-
- NAME
- MatchToolValue - check a tool type variable for a particular value.
-
- SYNOPSIS
- result = MatchToolValue(typeString, value)
- D0 A0 A1
-
- BOOL MatchToolValue(char *, char *);
-
- FUNCTION
- MatchToolValue is useful for parsing a tool type value for
- a known value. It knows how to parse the syntax for a tool
- type value (in particular, it knows that '|' separates
- alternate values). Note that the parsing is case insensitve.
-
- INPUTS
- typeString - a ToolType value (as returned by FindToolType)
- value - you are interested if value appears in typeString
-
- RESULTS
- result - TRUE if the value was in typeString else FALSE.
-
- EXAMPLE
- Assume there are two type strings:
- type1 = "text"
- type2 = "a|b|c"
-
- MatchToolValue( type1, "text" ) returns TRUE
- MatchToolValue( type1, "TEXT" ) returns TRUE
- MatchToolValue( type1, "data" ) returns FALSE
- MatchToolValue( type2, "a" ) returns TRUE
- MatchToolValue( type2, "b" ) returns TRUE
- MatchToolValue( type2, "d" ) returns FALSE
- MatchToolValue( type2, "a|b" ) returns FALSE

-
- NAME
- PutDefDiskObject - write disk object as the default for its type. (V36)
-
- SYNOPSIS
- status = PutDefDiskObject(diskobj)
- D0 A0
-
- BOOL PutDefDiskObject(struct DiskObject *);
-
- FUNCTION
- This routine writes out a DiskObject structure, and its
- associated information. If the call fails, a zero will
- be returned. The reason for the failure may be obtained
- via IoErr().
-
- Note that this function calls PutDiskObject internally which means
- that this call (if sucessful) notifies workbench than an icon has
- been created/modified.
-
- Using this routine protects you from any future changes to
- the way default icons are stored within the system.
-
- INPUTS
- diskobj -- a pointer to a DiskObject
-
- RESULTS
- status -- TRUE if the call succeeded else FALSE
-

-
- NAME
- PutDiskObject - write out a DiskObject to disk.
-
- SYNOPSIS
- status = PutDiskObject(name, diskobj)
- D0 A0 A1
-
- BOOL PutDiskObject(char *, struct DiskObject *);
-
- FUNCTION
- This routine writes out a DiskObject structure, and its
- associated information. The file name of the info
- file will be the name parameter with a
- ".info" postpended to it. If the call fails, a zero will
- be returned. The reason for the failure may be obtained
- via IoErr().
-
- As of release V2.0, PutDiskObject (if sucessful) notifies workbench
- han an icon has been created/modified.
-
- Using this routine protects you from any future changes to
- the way icons are stored within the system.
-
- INPUTS
- name -- name of the object (pointer to a character string)
- diskobj -- a pointer to a DiskObject
-
- RESULTS
- status -- TRUE if the call succeeded else FALSE
-
- NOTES
- It is recommended that if you wish to copy an icon from one place
- to another than you use GetDiskObject() and PutDiskObject()
- and do not copy them directly.
