- NAME
- BOpen -- open a file for bufferd IO.
-
- SYNOPSYS
- file = BOpen( name, accesmode )
-
- struct BuffIO *file;
- char *name;
- ULONG accessmode;
-
- FUNCTION
- To setup a "BuffIO" file handle and to open the file for you.
-
- INPUTS
- name - A pointer to a null terminated string which should be the
- full AmigaDOS name of the file you want to open.
- accessmode - The acces-mode of the file you want to open. Currently only
- "MODE_OLDFILE" and "MODE_NEWFILE" are supported.
-
- RESULT
- file will be a pointer to the "BuffIO" file handle or null if something
- went wrong.
-
- BUGS
- None known.

-
- NAME
- BClose -- close a "BuffIO" file handle.
-
- SYNOPSYS
- error = BClose( file )
-
- LONG error;
- struct BuffIO *file;
-
- FUNCTION
- To flush it's internal buffer and close the file. Then deallocate the
- "BuffIO" file handle.
-
- INPUTS
- file - A pointer to the "BuffIO" file handle which you want to close.
-
- RESULT
- The return code needs only to be checked when the handle was used to
- write to (MODE_NEWFILE). This is because this routines writes all data
- left in the buffer to the file before it's closed.
-
- BUGS
- None known.

- ascii.s/BIoErr ascii.s/BIoErr
-
- NAME
- BIoErr -- determine the last error of the file.
-
- SYNOPSYS
- error = BIoErr( file )
-
- LONG error;
- struct BuffIO *file;
-
- FUNCTION
- To take the last error from the "BuffIO" file handle and return it to
- you.
-
- INPUTS
- file - A pointer to the "BuffIO" file handle of which you want to know
- it's error status.
-
- RESULT
- error will be one of the following values :
-
- ASE_OK - everything OK
- ASE_EOF - everything OK but at end-of-file.
- ASE_NOMEM - out of memory
- ASE_READ - read error
- ASE_WRITE - write error
- ASE_NOFILE - obsolete (will never happen!)
- ASE_FILETYPE - tryed to write to MODE_OLDFILE or viceversa
-
- BUGS
- None known.
-
-
- ascii.s/BGetC ascii.s/BGetC
-
- NAME
- BGetC -- get one byte from a "BuffIO" file handle.
-
- SYNOPSYS
- byte = BGetC( file )
-
- LONG byte;
- struct BuffIO *file;
-
- FUNCTION
- To get one byte from the "BuffIO" file handle. If there arn't any bytes
- left in the buffer it will try to fill the buffer with data first.
-
- INPUTS
- file - A pointer to the "BuffIO" handle you want to get one byte from.
-
- RESULT
- byte should be the byte from the "BuffIO" handle (0-255). If the routine
- returned ASE_EOF you should make a call to "BIoErr()" to check wether or
- not there was an error.
-
- BUGS
- None known.
-
- SEE ALSO
- ascii.s/BIoErr()
-
-
- ascii.s/BPutC ascii.s/BPutC
-
- NAME
- BPutC -- write one byte to a "BuffIO" file handle.
-
- SYNOPSYS
- error = BPutC( file, byte )
-
- LONG error;
- struct BuffIO *file;
- ULONG byte;
-
- FUNCTION
- To put a byte in the "BuffIO" handle it's buffer. If the buffer was full
- it first writes the data in the buffer to the file and then puts the
- byte in the buffer.
-
- INPUTS
- file - A pointer to the "BuffIO" file handle to which you want to write
- a byte.
- byte - The byte (0-255) you want to write.
-
- RESULT
- Although most of the times "error" will read ASE_OK you should check the
- return code once in a while to see if the writing of the buffer to the
- file went OK.
-
- BUGS
- None known.
-
-
- ascii.s/AllocAscii ascii.s/AllocAscii
-
- NAME
- AllocAscii -- allocate a "AsciiText" structure.
-
- SYNOPSYS
- ascii = AllocAscii( tabsize, maxchars, flags )
-
- struct AsciiText *ascii;
- ULONG tabsize;
- ULONG maxchars;
- ULONG flags;
-
- FUNCTION
- To allocate an "AsciiText" structure and to initialize it with your
- preferred settings.
-
- INPUTS
- tabsize - The size of one tabstop.
- maxchars - The maximum amount of characters allowed in one line. A
- minimum of 5 and a maximum of 256 are allowed here.
- flags - Flag bits. These two are allowed here :
-
- ATF_SkipEsc - This tells "BGetS" not to count escape
- sequences as printable characters.
- ATF_TabConvert - This tells "BGetS" to convert TABS into
- blanks.
-
- RESULT
- ascii will be a pointer to an AsciiText structure or null if there the
- structure could not be allocated.
-
- BUGS
- None known.
-
-
- ascii.s/FreeAscii ascii.s/FreeAscii
-
- NAME
- FreeAscii -- deallocate an AsciiText structure.
-
- SYNOPSYS
- FreeAscii( ascii )
-
- struct AsciiText *ascii;
-
- FUNCTION
- To deallocate the memory of the text in the AsciiText structure and the
- memory of the AsciiText structure itself.
-
- INPUTS
- ascii - A pointer to the AsciiText structure you want to deallocate.
-
- BUGS
- None known.
-
-
- ascii.s/BGetS ascii.s/BGetS
-
- NAME
- BGetS -- get one line of text from the "BuffIO" handle.
-
- SYNOPSYS
- line = BGetS( file, ascii );
-
- struct Line *line;
- struct BuffIO *file;
- struct AsciiText *ascii;
-
- FUNCTION
- To allocate a line structure and read a complete text line. If the line
- contains more bytes than specified by you with "AllocAscii()" the line
- will be truncated with a NEWLINE and the LNF_Split flag will be set in
- the line. This means that such a line contains "line->Size - 1" bytes of
- actual data and one inserted NEWLINE.
-
- INPUTS
- file - A pointer to the BuffIO file handle in from which the line will
- be read.
- ascii - A pointer to the AsciiText structure in which the memory for the
- line will be allocated.
-
- RESULT
- line will be a pointer to the Line structure or null if the routine
- failed. NOTE: The line will not be added to the text itself. You must
- "AddTail(ascii,line)" it to do so. Do NOT add a line allocated in one
- AsciiText structure to another AsciiText structure!
-
- BUGS
- The routine chokes when the "ATF_SkipEsc" flag is set and the line has
- more than "MAXLINE" characters + escape sequences in it. If this is the
- case it will overflow it's internal buffer.

-
- SYNOPSYS
- error = BPutS( file, line )
-
- LONG error;
- struct BuffIO *file;
- struct Line *line;
-
- FUNCTION
- Write out the specified line to the "BuffIO" file handle. The routine
- writes "line->Size" bytes of data from normal lines and "line->Size - 1"
- bytes of data from lines with the LNF_Split flag set.
-
- INPUTS
- file - A pointer to the "BuffIO" file handle to which the line is
- written.
- line - A pointer to the "Line" structure which must be written.
-
- RESULT
- error is ASE_OK if everything went OK or something else if an error has
- occurred.

-
- FUNCTION
- To find the first occurrence of a specific string in a text. The routine

- RESULT
- found reads TRUE if the routine has found the string looked for and
- FALSE if not. If the routine returns TRUE the StringScan structure
- contains the specific position where it has found the string.
