PROLOG
       This  manual  page  is part of the POSIX Programmer's Manual.  The Linux implementation of this interface
       may differ (consult the corresponding Linux manual page for details of Linux behavior), or the  interface
       may not be implemented on Linux.


NAME
       memccpy — copy bytes in memory


SYNOPSIS
       #include <string.h>

       void *memccpy(void *restrict s1, const void *restrict s2,
           int c, size_t n);


DESCRIPTION
       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.


RETURN VALUE
       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.


ERRORS
       No errors are defined.

       The following sections are informative.


EXAMPLES
       None.


APPLICATION USAGE
       The memccpy() function does not check for the overflow of the receiving memory area.


RATIONALE
       None.


FUTURE DIRECTIONS
       None.
