Not implemented
IEEE Std 1003.1-2017
The memccpy() function shall copy bytes from memory area s2 into s1, stopping after the first occurrence of byte
c (converted to a unsigned char) is copied, or after n bytes are copied, whichever comes first. If copying takes
place between objects that overlap, the behavior is undefined.
The memccpy() function shall return a pointer to the byte after the copy of c in s1, or a null pointer if c
was not found in the first n bytes of s2.
No errors are defined.
