.TH STPCPY 3 1995-09-03 "GNU" "Linux Programmer's Manual"
|
|
.SH NAME
|
|
stpcpy \- copy a string returning a pointer to its end
|
|
.SH SYNOPSIS
|
|
.nf
|
|
.B #define _GNU_SOURCE
|
|
.br
|
|
.B #include <string.h>
|
|
.sp
|
|
.BI "char *stpcpy(char *" dest ", const char *" src );
|
|
.fi
|
|
.SH DESCRIPTION
|
|
The
|
|
.BR stpcpy ()
|
|
function copies the string pointed to by \fIsrc\fP
|
|
(including the terminating \(aq\\0\(aq character) to the array pointed to by
|
|
\fIdest\fP.
|
|
The strings may not overlap, and the destination string
|
|
\fIdest\fP must be large enough to receive the copy.
|
|
.SH "RETURN VALUE"
|
|
.BR stpcpy ()
|
|
returns a pointer to the \fBend\fP of the string
|
|
\fIdest\fP (that is, the address of the terminating null byte)
|
|
rather than the beginning.
|
|
.SH "CONFORMING TO"
|
|
This function is not part of the C or POSIX.1 standards, and is
|
|
not customary on Unix systems, but is not a GNU invention either.
|
|
Perhaps it comes from MS-DOS.
|
|
.SH EXAMPLE
|
|
For example, this program uses
|
|
.BR stpcpy ()
|
|
to concatenate \fBfoo\fP and
|
|
\fBbar\fP to produce \fBfoobar\fP, which it then prints.
