The ImpersonateNamedPipeClient function impersonates a named-pipe client application.
BOOL ImpersonateNamedPipeClient(
HANDLE hNamedPipe // handle of a named pipe
);
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
The ImpersonateNamedPipeClient function allows the server end of a named pipe to impersonate the client end. When this function is called, the named-pipe file system changes the thread of the calling process to start impersonating the security context of the last message read from the pipe. Only the server end of the pipe can call this function.
The server can call the RevertToSelf function when the impersonation is complete.
