       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.

       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.

       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);
       }

       stpcpy - copy a string returning a pointer to its end

stpcpy()  returns  a  pointer to the end of the string dest (that is, the address of the terminating null
       byte) rather than the beginning.
