       void *bsearch( void *key, void *base, int nelem, int width,
                       int (*fcmp )())

       - prototype in stdlib.h

       - does binary search for items in a table which is
         ALREADY sorted in ascending order
       - base points to 0th element of table
       - nelem contains number of entries in table
       - width contains number of bytes in each entry
       - key points to the search key

       - fcmp() points to comparison routine, where key and elem are
         passed to it as pointers.  Function fcmp() returns:

               integer < 0 if search key < elem;
               integer = 0 if equal;
               returns > 0 if search key > elem

       - returns 0 if no match found, else address of first
         entry that matches
