mempcpy, wmempcpy - copy memory area
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.
mempcpy() first appeared in glibc in version 2.1.
This function is a GNU extension.
