You don't have much alternative than doing that if you use 
GDALCreateAndReprojectImage(). But GDALCreateAndReprojectImage() is a 
"simplistic" warp API that doesn't have all the bells and whistles of 
what gdalwarp lib. You could potentially submit a patch to 
GDALCreateAndReprojectImage() to set the nodata value, which would be 
reasonable, but perhaps you could just bind the GDALWarp() C function 
that is the heart of the gdalwarp binary. You'd get all the advanced 
heuristics of gdalwarp that you don't get with the less advanced warp 
functions.
