NAME

6       memccpy - copy bytes in memory
7

SYNOPSIS

9       #include <string.h>
10
11       void *memccpy(void *restrict s1, const void *restrict s2,
12              int c, size_t n);

DESCRIPTION

16       The  memccpy()  function  shall copy bytes from memory area s2 into s1,
17       stopping after the first occurrence of byte c (converted to an unsigned
18       char) is copied, or after n bytes are copied, whichever comes first. If
19       copying takes place between objects that overlap, the behavior is unde‐
20       fined.
21

RETURN VALUE

23       The  memccpy()  function  shall  return a pointer to the byte after the
24       copy of c in s1, or a null pointer if c was not found in  the  first  n
25       bytes of s2.
