typedef EFI_PXE_BASE_CODE_CALLBACK_STATUS(EFIAPI * EFI_PXE_CALLBACK)(IN EFI_PXE_BASE_CODE_CALLBACK_PROTOCOL *This, IN EFI_PXE_BASE_CODE_FUNCTION Function, IN BOOLEAN Received, IN UINT32 PacketLen, IN EFI_PXE_BASE_CODE_PACKET *Packet) |
Callback function that is invoked when the PXE Base Code Protocol is about to transmit, has received, or is waiting to receive a packet.
This function is invoked when the PXE Base Code Protocol is about to transmit, has received, or is waiting to receive a packet. Parameters Function and Received specify the type of event. Parameters PacketLen and Packet specify the packet that generated the event. If these fields are zero and NULL respectively, then this is a status update callback. If the operation specified by Function is to continue, then CALLBACK_STATUS_CONTINUE should be returned. If the operation specified by Function should be aborted, then CALLBACK_STATUS_ABORT should be returned. Due to the polling nature of UEFI device drivers, a callback function should not execute for more than 5 ms. The SetParameters() function must be called after a Callback Protocol is installed to enable the use of callbacks.
This | The pointer to the EFI_PXE_BASE_CODE_CALLBACK_PROTOCOL instance. | |
Function | The PXE Base Code Protocol function that is waiting for an event. | |
Received | TRUE if the callback is being invoked due to a receive event. FALSE if the callback is being invoked due to a transmit event. | |
PacketLen | The length, in bytes, of Packet. This field will have a value of zero if this is a wait for receive event. | |
Packet | If Received is TRUE, a pointer to the packet that was just received; otherwise a pointer to the packet that is about to be transmitted. |
