NAME
       mempcpy, wmempcpy  - copy memory area

SYNOPSIS
       #define _GNU_SOURCE
       #include 

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

       #define _GNU_SOURCE
       #include 

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

DESCRIPTION
       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.

RETURN VALUE
       dest + n.

CONFORMING TO
       This function is a GNU extension.

EXAMPLE
       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;
       }
