.SH SYNOPSIS
|

.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
|

compatibility with XPG3 applications. Reliable error
|
|
|
|
detection by this function was never guaranteed.
