NET_Packet packet; uint16_t data = 1234; packet.w_u16(data);In this example, a new NET_Packet object is created and a 16-bit unsigned integer with a value of 1234 is written to the packet using the w_u16 function. Based on the function name and syntax, it is likely that NET_Packet is part of a larger network communication library. It could be part of a custom library developed by a company or individual, or it may be a part of a larger language-specific library for handling network communication in C++.
