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;
}
