void *memccpy(void *__restrict__ s1, const void *__restrict__ s2, int c, size_t n);General description
The memccpy() function copies bytes from memory area s2 into memory area s1, stopping after the first occurrence of byte c (converted to an unsigned char) is copied, or after n bytes are copied, whichever comes first.
Returned value
If successful, memccpy() returns a pointer to the byte after the copy of c in s1.
If c was not found in the first n bytes of s2, memccpy() returns a NULL pointer.
