stpcpy - copy a string returning a pointer to its end
char *stpcpy(char *dest, const char *src);
Feature Test Macro Requirements for glibc (see
- Since glibc 2.10:
_XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
- Before glibc 2.10:
function copies the string pointed to by
(including the terminating null byte ('\0')) to the array pointed to by
The strings may not overlap, and the destination string
must be large enough to receive the copy.
returns a pointer to the
of the string
(that is, the address of the terminating null byte)
rather than the beginning.
Multithreading (see pthreads(7))
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.
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
For example, this program uses
which it then prints.
char *to = buffer;
to = stpcpy(to, "foo");
to = stpcpy(to, "bar");
