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.

And for comparison here is the result of the same benchmark run on an Athlon X2 5000 (2.5Ghz), running 32-bit code:
