NAME explain_fseeko_or_die - seek to or report file position and report errors
SYNOPSIS #include <libexplain/fseeko.h> void explain_fseeko_or_die(FILE *fp, off_t offset, int whence); int explain_fseeko_on_error(FILE *fp, off_t offset, int whence);
DESCRIPTION The explain_fseeko_or_die function is used to call the fseeko(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_fseeko(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_fseeko_on_error function is used to call the fseeko(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_fseeko(3) function, but still returns to the caller. fp The fp, exactly as to be passed to the fseeko(3) system call. offset The offset, exactly as to be passed to the fseeko(3) system call. whence The whence, exactly as to be passed to the fseeko(3) system call.
RETURN VALUE The explain_fseeko_or_die function only returns on success, see fseeko(3) for more infor‐ mation. On failure, prints an explanation and exits, it does not return. The explain_fseeko_on_error function always returns the value return by the wrapped fseeko(3) system call.
EXAMPLE The explain_fseeko_or_die function is intended to be used in a fashion similar to the fol‐ lowing example: explain_fseeko_or_die(fp, offset, whence);
