spinel_eui64_t struct

Decodes and reads an EUI64 value form the frame. On success, the read position gets updated and the EUI64 value is copied into the given output variable.

Encodes and writes an EUI64 value to current input frame. Before using this method `BeginFrame()` must be called to start and prepare a new input frame. Otherwise, this method does nothing and returns error status `OT_ERROR_INVALID_STATE`. If no buffer space is available, this method will discard and clear the current input frame and return the error status `OT_ERROR_NO_BUFS`.
