Description

According to the man page, mempcpy() 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.function copies n bytes from memory area src to memory area dest.. It returns dest + n.

Due to the similarities with memcpy(), the functions operate nearly identical -in fact the code is usually the same, with only the return value changing.
