MEMPCPY(3)                 Linux Programmer's Manual                MEMPCPY(3)

       mempcpy, wmempcpy  - copy memory area

       #define _GNU_SOURCE         /* See feature_test_macros(7) */
       #include <string.h>

       void *mempcpy(void *dest, const void *src, size_t n);

       #define _GNU_SOURCE         /* See feature_test_macros(7) */
       #include <wchar.h>

       wchar_t *wmempcpy(wchar_t *dest, const wchar_t *src, size_t n);

       The  mempcpy()  function is nearly identical to the memcpy(3) function.
       It copies n bytes from the object beginning  at  src  into  the  object
       pointed  to  by  dest.   But  instead of returning the value of dest it
       returns a pointer to the byte following the last written byte.

       This function is useful in situations where a number of  objects  shall
       be copied to consecutive memory positions.

       The  wmempcpy()  function is identical but takes wchar_t type arguments
       and copies n wide characters.

       dest + n.

       mempcpy() first appeared in glibc in version 2.1.

   Multithreading (see pthreads(7))
       The mempcpy() and wmempcpy() functions are thread-safe.

       This function is a GNU extension.

       void *
       combine(void *o1, size_t s1, void *o2, size_t s2)
           void *result = malloc(s1 + s2);
           if (result != NULL)
               mempcpy(mempcpy(result, o1, s1), o2, s2);
           return result;

       memccpy(3), memcpy(3), memmove(3), wmemcpy(3)
