STPCPY(3) Linux Programmer's Manual STPCPY(3)
stpcpy - copy a string returning a pointer to its end
#include <string.h>
char *stpcpy(char *dest, const char *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);
