getProvider
Returns an IOService object's primary provider.
Declaration
virtual IOService * getProvider(
void ) const;Return Value
The first provider of the client, or zero if the IOService object is not attached into the I/O Registry. The provider is retained while the client is attached, and should not be released by the caller.
Overview
This function called in an IOService client will return the provider to which it was first attached. Because the majority of IOService objects have only one provider, this is a useful simplification and also supports caching of the provider when the I/O Registry is unchanged.
