void *memccpy(void *restrict s1, const void *restrict
int c, size_t n);
The memccpy() function shall copy bytes from memory area s2 into 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. 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.
The following sections are informative.
The memccpy() function does not check for the overflow of the receiving memory area.
