In your interpretation of the C99 standard: can you please tell, regarding
this sentence in section 7.21.5.1, and assuming a call memchr(ptr,c,n) with
ptr != NULL and n >= 0:

  "The memchr function returns a pointer to the located character, or a null 
pointer
   if the character does not occur in the object."

What is "the object"? Where does it start? Where does it end? How many 
"characters"
does it contain?
