void explain_setbuf_on_error(FILE *fp, char *data);
DESCRIPTION
The explain_setbuf_or_die function is used to call the setbuf(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_setbuf(3) function, and then the process terminates by calling exit(EXIT_FAILURE).The explain_setbuf_on_error function is used to call the setbuf(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_setbuf(3) function, but still returns to the caller.
- fp
- The fp, exactly as to be passed to the setbuf(3) system call.
- data
