pack_fseek(3) Allegro manual pack_fseek(3) NAME pack_fseek - Seeks inside a stream. Allegro game programming library. SYNOPSIS #include <allegro.h> int pack_fseek(PACKFILE *f, int offset); DESCRIPTION Moves the position indicator of the stream `f'. Unlike the standard fseek() function, this only supports forward movements relative to the current position and in read-only streams, so don't use negative off- sets. Note that seeking is very slow when reading compressed files, and so should be avoided unless you are sure that the file is not com- pressed. Example: input_file = pack_fopen("data.bin", "r"); if (!input_file) abort_on_error("Couldn't open binary data!"); /* Skip some useless header before reading data. */ pack_fseek(input_file, 32); RETURN VALUE Returns zero on success or a negative number on error, storing the er- ror code in `errno'.
