+.SH NAME
+strcat \- concatenate two strings
+.SH SYNOPSIS
+.LP
+\fB#include <string.h>

+.sp
+char *strcat(char *restrict\fP \fIs1\fP\fB, const char *restrict\fP
+\fIs2\fP\fB);

+.SH DESCRIPTION
+.LP
+The \fIstrcat\fP() function shall append a copy of the string pointed
+to by \fIs2\fP (including the terminating null byte) to
+the end of the string pointed to by \fIs1\fP. The initial byte of
+\fIs2\fP overwrites the null byte at the end of \fIs1\fP. If
+copying takes place between objects that overlap, the behavior is
+undefined.
+.SH RETURN VALUE
+.LP
+The \fIstrcat\fP() function shall return \fIs1\fP; no return value
+is reserved to indicate an error.
+.SH ERRORS
+.LP
+No errors are defined.
+.LP
+\fIThe following sections are informative.\fP
+.SH EXAMPLES
+.LP
+None.
+.SH APPLICATION USAGE
+.LP
+This issue is aligned with the ISO\ C standard; this does not affect
+compatibility with XPG3 applications. Reliable error
+detection by this function was never guaranteed.
+.SH RATIONALE
+.LP
+None.
+.SH FUTURE DIRECTIONS
+.LP
+None.
