GetGPE (Windows Embedded CE 6.0)

1/6/2010

This function executes in the GPE library while processing the DrvEnablePDEV and DrvGetModes DDI functions. The developer must provide this function.

Syntax

GPE* GetGPE(void);

Parameters

None.

Return Value

GPE class pointer.

Remarks

The display driver should create an instance of its GPE-derived class using new and return the resulting class pointer. The display driver should also save the class pointer in a global variable and check the value of that global variable before creating an instance of the GPE-derived class. For example, you can call this function multiple times, but it should only create one instance of its GPE-derived class.

The following is sample code from the flat driver.

// Main entry point for a GPE-compliant driver
//
static GPE gGPE = (GPE)NULL;
GPE* GetGPE(void)
{
if (!gGPE)
 {
  gGPE = new GPEFlat();
 }
return gGPE;
}
