al_fseek (3alleg5)

• #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 \[aq]whence\[aq], plus \[aq]offset\[aq] number of bytes.

\[aq]whence\[aq] can be:

\[bu]

ALLEGRO_SEEK_SET - seek relative to beginning of file

\[bu]

ALLEGRO_SEEK_CUR - seek relative to current file position

\[bu]

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.
