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

explain_socketpair_or_die - create pair of connected sockets and report errors
SYNOPSIS
#include <libexplain/socketpair.h>
void explain_socketpair_or_die(int domain, int type, int protocol, int *sv);
int explain_socketpair_on_error(int domain, int type, int protocol, int *sv);
DESCRIPTION
The explain_socketpair_or_die function is used to call the socketpair(2) system call. On failure an explanation will be printed to stderr,
obtained from the explain_socketpair(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_socketpair_on_error function is used to call the socketpair(2) system call. On failure an explanation will be printed to
stderr, obtained from the explain_socketpair(3) function, but still returns to the caller.
domain The domain, exactly as to be passed to the socketpair(2) system call.
type The type, exactly as to be passed to the socketpair(2) system call.
protocol
The protocol, exactly as to be passed to the socketpair(2) system call.
sv The sv, exactly as to be passed to the socketpair(2) system call.
RETURN VALUE
The explain_socketpair_or_die function only returns on success, see socketpair(2) for more information. On failure, prints an explanation
and exits, it does not return.
The explain_socketpair_on_error function always returns the value return by the wrapped socketpair(2) system call.
EXAMPLE
The explain_socketpair_or_die function is intended to be used in a fashion similar to the following example:
explain_socketpair_or_die(domain, type, protocol, sv);
