PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux

NAME

13       memccpy — copy bytes in memory
14

SYNOPSIS

16       #include <string.h>
17
18       void *memccpy(void *restrict s1, const void *restrict s2,
19           int c, size_t n);
20

DESCRIPTION

22       The memccpy() function shall copy bytes from memory area  s2  into  s1,
23       stopping after the first occurrence of byte c (converted to an unsigned
24       char) is copied, or after n bytes are copied, whichever comes first. If
25       copying takes place between objects that overlap, the behavior is unde‐
26       fined.
27

RETURN VALUE

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