On failure an explanation will be printed to stderr, obtained from the explain_fsetpos(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

On failure an explanation will be printed to stderr, ob- tained from the explain_fsetpos(3) function, but still returns to the caller. fp The fp, exactly as to be passed to the fsetpos(3) system call. pos The pos, exactly as to be passed to the fsetpos(3) system call.
