NAME
explain_tcflow_or_die - terminal flow control and report errors
SYNOPSIS
#include <libexplain/tcflow.h>
void explain_tcflow_or_die(int fildes, int action);
int explain_tcflow_on_error(int fildes, int action);
DESCRIPTION
The explain_tcflow_or_die function is used to call the tcflow(3) system
call. On failure an explanation will be printed to stderr, obtained
from the explain_tcflow(3) function, and then the process terminates by
calling exit(EXIT_FAILURE).
The explain_tcflow_on_error function is used to call the tcflow(3)
system call. On failure an explanation will be printed to stderr,
obtained from the explain_tcflow(3) function, but still returns to the
caller.
fildes The fildes, exactly as to be passed to the tcflow(3) system
call.
action The action, exactly as to be passed to the tcflow(3) system
call.
RETURN VALUE
The explain_tcflow_or_die function only returns on success, see
tcflow(3) for more information. On failure, prints an explanation and
exits, it does not return.
The explain_tcflow_on_error function always returns the value return by
the wrapped tcflow(3) system call.
EXAMPLE
The explain_tcflow_or_die function is intended to be used in a fashion
similar to the following example:
explain_tcflow_or_die(fildes, action);
