.TH COMERRNO 3 "15. Juli 1988" "J\*org Schilling" "Schily\'s LIBRARY FUNCTIONS"
|
||
|
|
.SH NAME
|
||
|
|
comerrno() \- prints error message, given error code, and
|
||
|
|
exits
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
.B
|
||
|
|
comerrno(error,format,args);
|
||
|
|
.B int error;
|
||
|
|
.B char *format;
|
||
|
|
.fi
|
||
|
|
.SH DESCRIPTION
|
||
|
|
comerrno() is like comerr(), except that the caller supplies the
|
||
|
|
error number. Positive numbers are turned into system error
|
||
|
|
messages. Negative numbers cause the system error portion of
|
||
|
|
the output to be omitted.
|
||
|
|
comerrno() is a convenient way to print the name of the program,
|
||
|
|
and an error message, and exit the process in a single call.
|
||
|
|
.SH RETURNS
|
||
|
|
none
|
||
|
|
.br
|
||
|
|
Rather than return, comerrno() exits the current process with a
|
||
|
|
value equal to the error number supplied by the user.
|
||
|
|
.SH EXAMPLES
|
||
|
|
.nf
|
||
|
|
if (argc < 2)
|
||
|
|
comerrno(-1, "Usage: name arg.\\n");
|
||
|
|
.fi
|
||
|
|
.SH "SEE ALSO"
|
||
|
|
comerr(3), error(3), errmsg(3), error(3) geterrno(3), printf(3), format(3)
|
||
|
|
.SH NOTES
|
||
|
|
comerrno() attempts to find a line in the message file that
|
||
|
|
corresponds to the system error number. If none can be found,
|
||
|
|
or if it has trouble finding or reading the file, it simply
|
||
|
|
says: error #.
