int *  covers 

Return ES_ERROR if error occurred in function.

Parameter covers returns non-zero if rast1 covers rast2

rast1: the first raster whose band will be tested
nband1: the 0-based band of raster rast1 to use if value is less than zero, bands are ignored. if nband1 gte zero, nband2 must be gte zero
rast2: the second raster whose band will be tested
nband2: the 0-based band of raster rast2 to use if value is less than zero, bands are ignored if nband2 gte zero, nband1 must be gte zero
