.TH catgets 3C "22 Mar 2002" "SunOS 5.11" "Standard C Library Functions"
.SH NAME
catgets \- read a program message
.SH SYNOPSIS
.LP
.nf
#include <nl_types.h>

\fBchar *\fR\fBcatgets\fR(\fBnl_catd\fR \fIcatd\fR, \fBint\fR \fIset_num\fR, \fBint\fR \fImsg_num\fR, \fBconst char *\fR\fIs\fR);
.fi

.SH DESCRIPTION
.sp
.LP
The \fBcatgets()\fR function attempts to read message \fImsg_num\fR, in set \fIset_num\fR, from the message catalog identified by  \fIcatd\fR. The \fIcatd\fR argument is a catalog descriptor returned from an earlier call to  \fBcatopen()\fR. The \fIs\fR argument points to a default message string which will be returned by  \fBcatgets()\fR if the identified message catalog is not currently available.
.SH RETURN VALUES
.sp
.LP
If the identified message is retrieved successfully,  \fBcatgets()\fR returns a pointer to an internal buffer area containing the  null terminated message string. If the call is unsuccessful for any reason, \fBcatgets()\fR returns a pointer to \fIs\fR and \fBerrno\fR may be set to indicate the error.
.SH ERRORS
