// versions of the Pocket PC. This function simply LoadLibrary's AYGSHELL
|
|
// and calls the function if it exists.
|
|
//
|
|
// ON ENTRY:
|
|
// SHUIMETRIC shuim: the metric to retrieve.
|
|
// PVOID pvBuffer: the retrieved data for the metric.
|
|
// DWORD cbBufferSize: the size of pvBuffer (should be sizeof(DWORD)).
|
|
// DWORD* pcbRequired: retrieves the minimum size of the buffer necessary
|
|
// to get the specified system UI metric. This can be NULL.
