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.

APPLICATION USAGE

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

RATIONALE

       None.

FUTURE DIRECTIONS
