memccpy — copy bytes in memory
[XSI] #include <string.h>
void *memccpy(void *restrict s1, const void *restrict s2,
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 not change the setting of errno on valid input.
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.
None.
The memccpy() function does not check for the overflow of the receiving memory area.
None.
None.

First released in Issue 1. Derived from Issue 1 of the SVID.
The restrict keyword is added to the memccpy() prototype for alignment with the ISO/IEC 9899:1999 standard.
Austin Group Defect 448 is applied, adding a requirement that memccpy() does not change the setting of errno on valid input.
