explain_tc...eak_or_die(3) Library Functions Manual explain_tc...eak_or_die(3) NAME explain_tcsendbreak_or_die - send terminal line break and report errors SYNOPSIS #include <libexplain/tcsendbreak.h> void explain_tcsendbreak_or_die(int fildes, int duration); int explain_tcsendbreak_on_error(int fildes, int duration); DESCRIPTION The explain_tcsendbreak_or_die function is used to call the tcsendbreak(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_tcsendbreak(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_tcsendbreak_on_error function is used to call the tcsend- break(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_tcsendbreak(3) function, but still returns to the caller. fildes The fildes, exactly as to be passed to the tcsendbreak(3) system call. duration The duration, exactly as to be passed to the tcsendbreak(3) system call. RETURN VALUE The explain_tcsendbreak_or_die function only returns on success, see tc- sendbreak(3) for more information. On failure, prints an explanation and exits, it does not return. The explain_tcsendbreak_on_error function always returns the value return by the wrapped tcsendbreak(3) system call. EXAMPLE The explain_tcsendbreak_or_die function is intended to be used in a fashion similar to the following example: explain_tcsendbreak_or_die(fildes, duration); SEE ALSO tcsendbreak(3) send terminal line break explain_tcsendbreak(3) explain tcsendbreak(3) errors exit(2) terminate the calling process COPYRIGHT libexplain version 1.3 Copyright (C) 2009 Peter Miller explain_tc...eak_or_die(3)
