<H2>DESCRIPTION</H2>
|
|
|
|
The
|
|
<B>stpcpy</B>()
|
|
|
|
function copies the string pointed to by
|
|
<I>src</I>
|
|
|
|
(including the terminating null byte ('\0')) to the array pointed to by
|
|
<I>dest</I>.
|
|
|
|
The strings may not overlap, and the destination string
|
|
<I>dest</I>
|
|
|
|
must be large enough to receive the copy.
|
|
<A NAME="lbAE"> </A>
|
|
<H2>RETURN VALUE</H2>
|
|
|
|
<B>stpcpy</B>()
|
|
|
|
returns a pointer to the
|
|
<B>end</B>
|
|
|
|
of the string
|
|
<I>dest</I>
|
|
|
|
(that is, the address of the terminating null byte)
|
|
rather than the beginning.

<H2>CONFORMING TO</H2>
|
|
|
|
This function was added to POSIX.1-2008.
|
|
Before that, it was not part of
|
|
the C or POSIX.1 standards, nor customary on UNIX systems.
|
|
It first appeared at least as early as 1986,
|
|
in the Lattice C AmigaDOS compiler,
|
|
then in the GNU fileutils and GNU textutils in 1989,
|
|
and in the GNU C library by 1992.
|
|
It is also present on the BSDs.
|
|
<A NAME="lbAH"> </A>
|
|
<H2>BUGS</H2>
|
|
|
|
This function may overrun the buffer
|
|
<I>dest</I>.
|
|
|
|
<A NAME="lbAI"> </A>
|
|
<H2>EXAMPLE</H2>
|
|
|
|
For example, this program uses
|
|
<B>stpcpy</B>()
|
|
|
|
to concatenate
|
|
<B>foo</B>
|
|
|
|
and
|
|
<B>bar</B>
|
|
|
|
to produce
|
|
<B>foobar</B>,
|
|
|
|
which it then prints.
