Routine Description:

|
Retreives device-independent bitmap data and a color table from a

bitmap in a resource.
|

|
Arguments:
|

|
hInst - supplies instance handle for module containing the bitmap resource.
|

|
|
|
||
|
|
Id - supplies the id of the bitmap resource.
|

|
|
|
||
|
|
Palette - if successful, receives a handle to a palette for the bitmap.
|
||
|
|
|
||
|
|
ColorCount - if successful, receives the number of entries in the
|
||
|
|
palette for the bitmap.

|
|
|
||
|
|
BitmapData - if successful, receives a pointer to the bitmap info

header structure in the resources. This is in read-only memory

so the caller should not try to modify it.
