explain_fflush_or_die(3) Library Functions Manual explain_fflush_or_die(3)NAME
explain_fflush_or_die - flush a stream and report errors
SYNOPSIS
#include <libexplain/fflush.h>
void explain_fflush_or_die(FILE *fp);
int explain_fflush_on_error(FILE *fp);
DESCRIPTION
The explain_fflush_or_die function is used to call the fflush(3) system call. On failure an explanation will be printed to stderr, obtained
from the explain_fflush(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_fflush_on_error function is used to call the fflush(3) system call. On failure an explanation will be printed to stderr,
obtained from the explain_fflush(3) function, but still returns to the caller.
fp The fp, exactly as to be passed to the fflush(3) system call.
RETURN VALUE
The explain_fflush_or_die function only returns on success, see fflush(3) for more information. On failure, prints an explanation and
exits, it does not return.
The explain_fflush_on_error function always returns the value return by the wrapped fflush(3) system call.
EXAMPLE
The explain_fflush_or_die function is intended to be used in a fashion similar to the following example:
explain_fflush_or_die(fp);
SEE ALSO fflush(3)
flush a stream
explain_fflush(3)
explain fflush(3) errors
exit(2) terminate the calling process
