stpcpy - copy a string returning a pointer to its end
char *stpcpy(char *dest, const char *src);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
Since glibc 2.10:
_XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
Before glibc 2.10:
The stpcpy() function copies the string pointed to by src (including
the terminating null byte (' ')) 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.
Multithreading (see pthreads(7))
The stpcpy() function is thread-safe.
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, but was
not a GNU invention either. Perhaps it came from MS-DOS. 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.
char *to = buffer;
to = stpcpy(to, "foo");
to = stpcpy(to, "bar");
