- FastFile
- --------
- FastFile provides a way to create a very fast way to access large numbers
- of files.
-
- You use FFCREATE.EXE to create a single flat file. Just run FFCREATE in
- the directory that contains all of the files you wish to access. A file
- will be created at the root (RESULT.FF) that is the FastFile. (you can
- specify a filename on the command line to override the default of RESULT.FF;
- if you do so, make sure that the result file is NOT generated in the
- current directory).
-
- Once you have created your FastFile, you can use the FastFile routines to
- access it:
-
- BOOL FastFileInit( LPSTR fname, int max_handles ):
- Call to initialize access to a FastFile.
- fname : name of FastFile
- max_handles: maximum number of file handles you want to have open at the
- same time.
- returns TRUE if succeeds, FALSE otherwise
-
- void FastFileFini( void ):
- Call when you are finished accessing your FastFile
-
- HFASTFILE FastFileOpen( LPSTR name ):
- Call to open an individual file in a FastFile (read-only access is supported)
- name: name if individual file
- returns a handle, or NULL if fail
-
- BOOL FastFileClose( HFASTFILE hff ):
- Call to close an individual file
- hff: handle to an individual file
- returns TRUE if succeeded, FALSE otherwise
-
- BOOL FastFileRead( HFASTFILE hff, LPVOID ptr, int size )
- Call to read from an individual file
- hff: handle to an individual file
- ptr: buffer to copy data
- size: size of data to copy
- returns TRUE if succeeded, FALSE otherwise
-
- BOOL FastFileSeek( HFASTFILE hff, int off, int type )
- Call to seek to an offset in an individual file
- hff: handle to an individual file
- off: offset to seek to
- type: seek type: SEEK_SET (from start), SEEK_CUR (from current pos),
- or SEEK_END (from end)
- returns TRUE if succeeded, FALSE otherwise
-
- long FastFileTell( HFASTFILE hff )
- Call to get the current position in an individual file
- hff: handle to an individual file
- returns current position if succeeded, -1 otherwise
