Here's one way:
const hssize_t coord[1][1]
coord[0][0] = attnum;
if (H5Sselect_elements(att_info_spaceid, H5S_SELECT_SET,
1, coord[0]) < 0)
but you had to stick a "const" in the declaration to make that work.
Without the const, you will get a warning, since you're passing in
something that is not const correct.
