  40 .In string.h
  41 .Ft void *
  42 .Fn memccpy "void *dst" "const void *src" "int c" "size_t len"
  43 .Sh DESCRIPTION
  44 The
  45 .Fn memccpy
  46 function
  47 copies bytes from string
  48 .Fa src
  49 to string
  50 .Fa dst .
  51 If the character
  52 .Fa c
  53 (as converted to an unsigned char) occurs in the string
  54 .Fa src ,
  55 the copy stops and a pointer to the byte after the copy of
  56 .Fa c
  57 in the string
  58 .Fa dst
  59 is returned.
  60 Otherwise,
  61 .Fa len
  62 bytes are copied, and a NULL pointer is returned.
