STPCPY(3) Linux Programmer's Manual STPCPY(3)
stpcpy - copy a string returning a pointer to its end
#include <string.h>
char *stpcpy(char *restrict dest, const char *restrict src);
Feature Test Macro Requirements for glibc (see
feature_test_macros(7)):
stpcpy():
Since glibc 2.10:
_POSIX_C_SOURCE >= 200809L
Before glibc 2.10:
_GNU_SOURCE
The stpcpy() function copies the string pointed to by src
(including the terminating null byte ('\0')) to the array pointed
to by dest. The strings may not overlap, and the destination
string dest must be large enough to receive the copy.
stpcpy() returns a pointer to the end of the string dest (that
is, the address of the terminating null byte) rather than the
beginning.
For an explanation of the terms used in this section, see
attributes(7).

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.
This function may overrun the buffer dest.
For example, this program uses stpcpy() to concatenate foo and
bar to produce foobar, which it then prints.
#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);
