Syntax
INT is_GetImageMem (HIDS hf, VOID** pMem)
Description
is_GetImageMem() returns the pointer to the start of the active image memory. In DirectDraw mode the pointer is returned to the back buffer (or the visible area - DirectDraw primary surface mode).

pMem |
Pointer to the beginning of the image memory |
Return value
