ERRMSGNO(3) Schily's LIBRARY FUNCTIONS ERRMSGNO(3)
NAME errmsgno() - prints error message, given error code
SYNOPSIS errmsgno (errcode, format, arg1...argn) int errcode; char *format;
DESCRIPTION errmsgno() prints an error output message corresponding to errcode, which is a standard system error. errmsgno() begins its output with the current program name (as passed to it by exec ). The message can be expanded with additional arguments in the same form printf() would.
RETURNS none
SEE ALSO comerr(3), comerrno(3), error(3), errmsg(3), error(3) geterrno(3), printf(3), format(3)
NOTES errmsgno() is identical to comerrno() except instead of exiting, it prints the error message and returns to the caller. If the errcode argument is positive, errmsgno() ignores it and just prints the program name and the result of expanding format().
