typedef struct _DD_MAPMEMORYDATA{

} DD_MAPMEMORYDATA;
The DD_MAPMEMORYDATA structure is passed to the DirectDraw hardware interface’s MapMemory object callback.
Members
lpDD
Pointer to the DD_DIRECTDRAW_GLOBAL structure that describes the driver.
bMap
Specifies the memory operation that the driver should perform. A value of TRUE indicates that the driver should map memory; FALSE means that the driver should unmap memory.
hProcess
Handle to the process whose address space is affected.
fpProcess
Pointer to the address in the process’s address space in which the memory mapping/unmapping occurs.
ddRVal
Location in which the driver returns a DirectDraw status return code. The status codes are defined in ddraw.h.
