Try something like this :
RLE_SPRITE my_sprite;
my_sprite = (RLE_SPRITE*)dataf_rle[spr_no].dat;
//and then to find height use
my_sprite->h;

The other way to do this is casting dataf_rle[spr_no] to RLE_SPRITE
((RLE_SPRITE*)dataf_rle[spr_no].dat)->h;

I am not really sure about this. I have never used REL_SPRITEs, but this
works with BITMAPs.
