;int strncmp(first, last, count) - compare first count chars of strings
;
;Purpose:
; Compares two strings for lexical order. The comparison stops
; after: (1) a difference between the strings is found, (2) the end
; of the strings is reached, or (3) count characters have been
; compared.
;
; Algorithm:
; int
; strncmp (first, last, count)
; char *first, *last;
; unsigned count;
; {
; if (!count)
; return(0);
; while (--count && *first && *first == *last)
; {
; first++;
; last++;
; }
; return(*first - *last);
; }
;
;Entry:
; char *first, *last - strings to compare
; unsigned count - maximum number of characters to compare
;
;Exit:
; returns <0 if first < last
; returns 0 if first == last
; returns >0 if first > last
;
