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);
