qt_double_max

SYNOPSIS

       #include <qthread/qloop.h>

       double
       qt_double_max(double *array, size_t length, int checkfeb);

       unsigned int
       qt_uint_max(unsigned int *array, size_t length, int checkfeb);

       int
       qt_int_max(int *array, size_t length, int checkfeb);

DESCRIPTION

       These functions take as input an  array  of  length  numbers  and  will
       return  the  maximum value within those numbers. This value is computed
       in parallel by dividing the possible  values  up  among  the  shepherds
       evenly, using futures to restrict the parallelism to the available lim-
       its.

       If checkfeb is non-zero, these functions will wait for the  entries  in
       the  array  to be full before comparing them. They DO NOT check whether
       the array entries are properly aligned.

RETURN VALUE

       The maximum value of the first length entries of array.
