NetSrv.exe - 11 error(s), 0 warning(s)
Analysis: Compile error-free, the connection is wrong, the first function is declared but there is no specific implementation, the second is not loaded into the required dynamic link library (lib library). This problem belongs to the second case.
solve:
(1) the header file: #include <Winsock2.h>
(2) the menu bar ---> project ----> Settings ----> Link tab ----> Object / library modules ----> added ws2_32.lib ----> recompile connection ----> resolved.
