This is just a guess, but you might try the following.

;--- declare image as a pointer to an array of byte type
image = ptr_new(bytarr(640,480))
image = call_external("C:\11ryan\temp\Debug\testDLL.dll","testDLL ")
window, xsize=640, ysize=480 ;--- open a window for display
tvscl, *image ;--- scale and display the contents of the image pointer

after the call_external, you might also issue
print, image
If it returns something like this <PtrHeapVar1> then it's certainly a pointer.
