       copystr	-  General:  Copies  a null-terminated character string with a
       specified limit

       int copystr(
	       char *s1,
	       char *s2,
	       u_int maxlength,
	       u_int *ncopiedaddr );

       Specifies a pointer to a string (an array of characters terminated by a
       null character).	 Specifies a pointer to a buffer of at least maxlength
       characters.  Specifies the maximum number of characters to copy.	 Spec‐
       ifies the address of an integer to receive the number of copied charac‐

       The copystr routine copies string s1 to the buffer pointed  to  by  s2.
       The  routine  stops  after  copying  a  null character or after copying
       maxlength characters, whichever comes  first.  The  s2  buffer  is  not
       padded with null characters to maxlength.

       The  copystr  routine  returns  the  number of characters copied in the
       location pointed to by ncopiedaddr. Note that the character size	 is  1

       Upon  successful completion, copystr returns the value 0 (zero). Other‐
       wise, it can return the following error: The string length, s1, exceeds
       the maximum number of characters, maxlength.

       Routines: bcopy(9r), blkclr(9r), ovbcopy(9r), strcpy(9r), strncpy(9r)
