Parameters

brbType [in]

Specifies a value from the BRB_TYPE enumeration to initialize the BRB with.

tag [in]

Specifies a 4-byte pool tag that uniquely identifies the driver that does the memory allocation. For more information about pool tags, see ExAllocatePoolWithTag.

Return value

BthAllocateBrb returns a pointer to the newly allocated BRB, or NULL if the system is out of memory.

Remarks

Profile drivers obtain a pointer to the BthAllocateBrb function when they query the Bluetooth driver stack for an instance of the BTHDDI_PROFILE_DRIVER_INTERFACE driver interface. See Querying for Bluetooth Interfaces for more information about querying the Bluetooth driver stack.
