- * bsearch.c
- * Original Author: G. Haley
- * Rewritten by: G. Noer
- *
- * Searches an array of nmemb members, the initial member of which is pointed
- * to by base, for a member that matches the object pointed to by key. The
- * contents of the array shall be in ascending order according to a comparison
- * function pointed to by compar. The function shall return an integer less
- * than, equal to or greater than zero if the first argument is considered to be
- * respectively less than, equal to or greater than the second. Returns a
- * pointer to the matching member of the array, or a null pointer if no match
- * is found.

-ANSI_SYNOPSIS
- #include <stdlib.h>
- void *bsearch(const void *<[key]>, const void *<[base]>,
- size_t <[nmemb]>, size_t <[size]>,
- int (*<[compar]>)(const void *, const void *));

- char *<[key]>;
- char *<[base]>;
- size_t <[nmemb]>, <[size]>;
- int (*<[compar]>)();
-
-DESCRIPTION
-<<bsearch>> searches an array beginning at <[base]> for any element
-that matches <[key]>, using binary search. <[nmemb]> is the element
-count of the array; <[size]> is the size of each element.
-
-The array must be sorted in ascending order with respect to the
-comparison function <[compar]> (which you supply as the last argument of
-<<bsearch>>).
-
-You must define the comparison function <<(*<[compar]>)>> to have two
-arguments; its result must be negative if the first argument is
-less than the second, zero if the two arguments match, and
-positive if the first argument is greater than the second (where
-``less than'' and ``greater than'' refer to whatever arbitrary
-ordering is appropriate).
-
-RETURNS
-Returns a pointer to an element of <[array]> that matches <[key]>. If
-more than one matching element is available, the result may point to
-any of them.
-
-PORTABILITY
-<<bsearch>> is ANSI.
-
-No supporting OS subroutines are required.

-FUNCTION
-<<qsort>>---sort an array
-
-INDEX
- qsort
-
-ANSI_SYNOPSIS
- #include <stdlib.h>
- void qsort(void *<[base]>, size_t <[nmemb]>, size_t <[size]>,
- int (*<[compar]>)(const void *, const void *) );
-
-TRAD_SYNOPSIS
- #include <stdlib.h>
- qsort(<[base]>, <[nmemb]>, <[size]>, <[compar]> )
- char *<[base]>;
- size_t <[nmemb]>;
- size_t <[size]>;
- int (*<[compar]>)();
-
-DESCRIPTION
-<<qsort>> sorts an array (beginning at <[base]>) of <[nmemb]> objects.
-<[size]> describes the size of each element of the array.
-
-You must supply a pointer to a comparison function, using the argument
-shown as <[compar]>. (This permits sorting objects of unknown
-properties.) Define the comparison function to accept two arguments,
-each a pointer to an element of the array starting at <[base]>. The
-result of <<(*<[compar]>)>> must be negative if the first argument is
-less than the second, zero if the two arguments match, and positive if
-the first argument is greater than the second (where ``less than'' and
-``greater than'' refer to whatever arbitrary ordering is appropriate).
-
-The array is sorted in place; that is, when <<qsort>> returns, the
-array elements beginning at <[base]> have been reordered.
-
-RETURNS
-<<qsort>> does not return a result.
-
-PORTABILITY
-<<qsort>> is required by ANSI (without specifying the sorting algorithm).
