.SH NAME
strcat, strncat \- concatenate two strings
.SH SYNOPSIS
.nf
.B #include <string.h>
.sp
.BI "char *strcat(char *" dest ", const char *" src );
.sp
.BI "char *strncat(char *" dest ", const char *" src ", size_t " n );

.SH DESCRIPTION
The \fBstrcat()\fP function appends the \fIsrc\fP string to the
\fIdest\fP string overwriting the `\\0' character at the end of
\fIdest\fP, and then adds a terminating `\\0' character. The
strings may not overlap, and the \fIdest\fP string must have
enough space for the result.
.PP
The \fBstrncat()\fP function is similar, except that only the first
\fIn\fP characters of \fIsrc\fP are appended to \fIdest\fP.
.SH "RETURN VALUE"
The \fBstrcat()\fP and \fBstrncat()\fP functions return a pointer
to the resulting string \fIdest\fP.
.SH "CONFORMING TO"
SVID 3, POSIX, BSD 4.3, ISO 9899
