template<typename DType>
void tt::tt_metal::v0::EnqueueReadBuffer(CommandQueue &cq, Buffer &buffer, std::vector<DType> &dst, bool blocking, tt::stl::Span<const SubDeviceId> sub_device_ids = {})

Reads a buffer from the device

Return value: void

Argument	Description	Type	Valid Range	Required
cq	The command queue object which dispatches the command to the hardware	CommandQueue &		Yes
buffer	The device buffer we are reading from	Buffer & or std::shared_ptr<Buffer>		Yes
dst	The vector where the results that are read will be stored	vector<DType> &		Yes
blocking	Whether or not this is a blocking operation	bool	Only blocking mode supported currently	Yes
sub_device_ids	The sub-device ids to wait for completion on. If empty, waits for all sub-devices	tt::stl::Span<const uint32_t>		No
