explain_setlinebuf_or_die(3) Library Functions Manual explain_setlinebuf_or_die(3)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);
SEE ALSO setlinebuf(3)
stream buffering operations
explain_setlinebuf(3)
explain setlinebuf(3) errors
exit(2) terminate the calling process
