Information Device Contexts
Windows supports an information device context used to retrieve default device
data. For example, an application can call the
CreateIC function to create an information device context for a particular model of
printer and then call the
GetCurrentObject and
GetObject functions to retrieve the default pen or brush attributes. Because Windows
can retrieve device information without creating the structures normally
associated with the other types of device contexts, an information device context
involves far less overhead and is created significantly faster than any of the other
types. After an application finishes retrieving data by using an information
device context, it must call the
DeleteDC function.
