al_fseek - Allegro 5 API


#include <allegro5/allegro.h>
bool al_fseek(ALLEGRO_FILE *f, int64_t offset, int whence)

    

Set the current position of the given file to a position relative to that specified by `whence', plus `offset' number of bytes.

`whence' can be:

ALLEGRO_SEEK_SET - seek relative to beginning of file
ALLEGRO_SEEK_CUR - seek relative to current file position
ALLEGRO_SEEK_END - seek relative to end of file

Returns true on success, false on failure. errno is set to indicate the error.

After a successful seek, the end-of-file indicator is cleared and all pushback bytes are forgotten.

On some platforms this function may not support large files.
