.SH DESCRIPTION

The

.BR stpcpy ()

function copies the string pointed to by

.I src

(including the terminating null byte (\(aq\\0\(aq)) to the array pointed to by

.IR dest .

The strings may not overlap, and the destination string

.I dest

must be large enough to receive the copy.

.SH RETURN VALUE

.BR stpcpy ()

returns a pointer to the

.B end

of the string

.I dest

(that is, the address of the terminating null byte)

rather than the beginning.

.SH CONFORMING TO

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.

.SH BUGS

This function may overrun the buffer

.IR dest .

.SH EXAMPLE

For example, this program uses

.BR stpcpy ()

to concatenate

.B foo

and

.B bar

to produce

.BR foobar ,

which it then prints.

.PP

.EX

#define _GNU_SOURCE

#include <string.h>

#include <stdio.h>

int

main(void)

{

    char buffer[20];

    char *to = buffer;

    to = stpcpy(to, "foo");

    to = stpcpy(to, "bar");

    printf("%s\\n", buffer);

}
