 NAME
    H5S_select_shape_same_test
 PURPOSE
    Determine if two dataspace selections are the same shape
 USAGE
    htri_t H5S_select_shape_same_test(sid1, sid2)
        hid_t sid1;          IN: 1st dataspace to compare
        hid_t sid2;          IN: 2nd dataspace to compare
 RETURNS
    Non-negative TRUE/FALSE on success, negative on failure
 DESCRIPTION
    Checks to see if the current selection in the dataspaces are the same
    dimensionality and shape.
 GLOBAL VARIABLES
 COMMENTS, BUGS, ASSUMPTIONS
