Communicates with a registered handler.
This function provides a service to send and receive messages from a registered UEFI service.
[in] | This | The EFI_SMM_COMMUNICATION_PROTOCOL instance. |
[in] | CommBuffer | A pointer to the buffer to convey into SMRAM. |
[in] | CommSize | The size of the data buffer being passed in.On exit, the size of data being returned. Zero if the handler does not wish to reply with any data. |
EFI_SUCCESS | The message was successfully posted. | |
EFI_INVALID_PARAMETER | The CommBuffer was NULL. |
