Are you using BinMem, or BinIO?
BinIO
Ah. BinIO is going to be a lot slower than BinMem, because it does
an hPutChar for each character, whereas BinMem just writes into an
array. I never really optimised the BinIO path, because we use

Dear all,
I try to use the following to convert [[Int]] to C's int[][] :

doCompForeign :: CString - CString - IO (Ptr (Ptr Int))
doCompForeign patraw cnameraw = let pat = peekCString patraw

int[][] is a very different type than [[Int]] is. An int[][]
is a pointer to an array of pointers to integers:
int[][] == int*[] == int**
