NAME

explain_setlinebuf_or_die - stream buffering operations and report errors  

SYNOPSIS

#include <libexplain/setlinebuf.h>

void explain_setlinebuf_or_die(FILE *fp);
void explain_setlinebuf_on_error(FILE *fp);  

DESCRIPTION

The explain_setlinebuf_or_die function is used to call the setlinebuf(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_setlinebuf(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

The explain_setlinebuf_on_error function is used to call the setlinebuf(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_setlinebuf(3) function, but still returns to the caller.

fp
The fp, exactly as to be passed to the setlinebuf(3) system call.
 

RETURN VALUE

The explain_setlinebuf_or_die function only returns on success, see setlinebuf(3) for more information. On failure, prints an explanation and exits, it does not return.

The explain_setlinebuf_on_error function always returns the value return by the wrapped setlinebuf(3) system call.  

EXAMPLE

The explain_setlinebuf_or_die function is intended to be used in a fashion similar to the following example:
explain_setlinebuf_or_die(fp);
