i need to create a named pipe for communication between client and server (in same host), here is the code:
WCHAR wszPipeName[MAX_FILE_LENGTH];
swprintf_s(wszPipeName, MAX_FILE_LENGTH, L"\\\\.\\pipe\\TEST%d", uniqueID);
pipe = CreateNamedPipe(
wszPipeName, // name of the pipe
PIPE_ACCESS_DUPLEX,
PIPE_TYPE_MESSAGE | PIPE_READMODE_MESSAGE | PIPE_NOWAIT,
1,
MAX_MSG_SIZE,
MAX_MSG_SIZE , //inbound buffer
MAX_READ_DATA_TIMEOUT,
NULL // use default security attributes
);
It the handler get back is always INVALID_HANDLE_VAULE, and the error is ERROR_ACCESS_DENIED.
Is there anything wrong here? It is running on Windows 7/8.
Thanks
Found the reason, it is because the security limitation. After providing a suitable security descriptor, it just works!
