xt_ff_seeko(3) Library Functions Manual xt_ff_seeko(3) NAME xt_ff_seeko() - Reposition file descriptor under a fast file stream LIBRARY #include <xtend/file.h> -lxtend SYNOPSIS int xt_ff_seeko(xt_ff_t *stream, off_t offset, int whence) ARGUMENTS stream Pointer to a xt_ff_t structure offset New position in bytes forward or backward from whence (positive or negative) whence SEEK_SET (beginning of file), SEEK_CUR (current position), or SEEK_END (end of file) DESCRIPTION xt_ff_seeko(3) repositions the file descriptor underlying stream to any position within the file, using lseek(2). It is analogous to fseeko(3). The stream must refer to a regular file, as pipes are not generally seekable. RETURN VALUES 0 on success, -1 on failure (errno set) EXAMPLES // Reposition so that 10th byte in the file is the next one read xt_ff_seeko(stream, 10, SEEK_SET); SEE ALSO fseek(3), lseek(2) xt_ff_seeko(3)
