Urgently asked a question about socket programming

With UDP protocol,
When sending data using the sendto (...) function, it always returns 1 instead of the number of bytes of data sent, but the receiver can receive the data correctly. Is that why?
Thanks a lot

Check the socket document you used. It may return 1 to indicate that the sending was successful, which is not the same as the general definition.

Is it winsock?
