stpcpy - copy a string returning a pointer to its end
char *stpcpy(char *dest, const char *src));
The stpcpy() function copies the string pointed to by src
(including the terminating `\0' character) to the array
pointed to by dest. The strings may not overlap, and the
destination string dest must be large enough to receive the
stpcpy() returns a pointer to the end of the string dest
(that is, the address of the terminating null character)
rather than the beginning.
For example, this program uses stpcpy to concatenate foo and
bar to produce foobar, which it then prints.
char *to = buffer;
to = stpcpy (to, "foo");
to = stpcpy (to, "bar");
printf ("%s\n", buffer);
This function is not part of the ANSI or POSIX standards,
and is not customary on Unix systems, but is not a GNU
invention either. Perhaps it comes from MS-DOS.
