.SH DESCRIPTION
|
2005-10-19 07:07:02 +00:00
|
|
|
The \fBstrcat\fP() function appends the \fIsrc\fP string to the
|
2004-11-03 13:51:07 +00:00
|
|
|
\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
|
2005-10-19 07:07:02 +00:00
|
|
|
The \fBstrncat\fP() function is similar, except that it will use
|
2004-11-03 13:51:07 +00:00
|
|
|
at most \fIn\fP characters from \fIsrc\fP.
|
|
|
|
Since the result is always terminated with `\\0', at most \fIn\fP+1
|
|
|
|
characters are written.
|
|
|
|
.SH "RETURN VALUE"
|
2005-10-19 07:07:02 +00:00
|
|
|
The \fBstrcat\fP() and \fBstrncat\fP() functions return a pointer
|
2004-11-03 13:51:07 +00:00
|
|
|
to the resulting string \fIdest\fP.
