.TH ERRMSG 3 "15. Juli 1988" "J\*org Schilling" "Schily\'s LIBRARY FUNCTIONS"
|
||
|
|
.SH NAME
|
||
|
|
errmsg() \- prints error message
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
.B
|
||
|
|
errmsg (format, arg1\|.\|.\|.argn)
|
||
|
|
.B char *format;
|
||
|
|
.fi
|
||
|
|
.SH DESCRIPTION
|
||
|
|
errmsg() prints on the error output stream, a message
|
||
|
|
corresponding to the last error encountered by the system on
|
||
|
|
behalf of the process. errmsg() 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 EXAMPLES
|
||
|
|

|
||
|
|
while (more_args) {
|
||
|
|
if (( f = fileopen(arg, "r")) == NULL) {
|
||
|
|
errmsg("Skipping file %s.\\n", arg);
|
||
|
|
continue;
|
||
|
|
}

.SH "SEE ALSO"
|
||
|
|
comerr(3), comerrno(3), error(3), geterrno(3), printf(3), format(3)
|
||
|
|
.SH NOTES
|
||
|
|
errmsg() is identical to comerr() except that instead of
|
||
|
|
exiting, errmsg() prints the error message and returns to the
|
||
|
|
caller.
