.TH ERRMSGNO 3 "15. Juli 1988" "J\*org Schilling" "Schily\'s LIBRARY FUNCTIONS"
.SH NAME
errmsgno() \- prints error message, given error code
.SH SYNOPSIS
.nf
.B
errmsgno (errcode, format, arg1\|.\|.\|.argn)
.B	int errcode;
.B	char *format;
.fi
.SH 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.
.SH RETURNS
none
.SH "SEE ALSO"
comerr(3), comerrno(3), error(3), errmsg(3), error(3) geterrno(3),
printf(3), format(3)
.SH 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().
