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);
