WNetGetUser

The WNetGetUser function retrieves the current default user name or the user name used to establish a network connection.

DWORD WNetGetUser(

LPCTSTR lpName,	// pointer to local name to get user name for
LPTSTR lpUserName,	// pointer to buffer for user name
LPDWORD lpnLength	// pointer to buffer size variable
);

Parameters

lpName

Points to a null-terminated string that specifies either the name of the local device that has been redirected to a network resource, or the remote name of a network resource to which a connection has been made.

If this parameter is NULL, Windows returns the name of the current user for the process.

lpUserName

Points to a buffer that receives the null-terminated user name.

lpnLength

Points to a variable that specifies the size, in characters, of the buffer pointed to by lpUserName. If the call fails because the buffer is not big enough, this variable contains the required buffer size.

Return Values

If the function succeeds, the return value is NO_ERROR.

If the function fails, the return value is an error code. To get extended error information, call GetLastError. GetLastError may return one of the following error codes:

Value	Meaning
ERROR_NOT_CONNECTED	The device specified by lpName is not a redirected device or a connected network name.
ERROR_MORE_DATA	More entries are available with subsequent calls.
ERROR_NO_NETWORK	No network is present.
ERROR_EXTENDED_ERROR	A network-specific error occurred. To get a description of the error, use the WNetGetLastError function.
ERROR_NO_NET_OR_BAD_PATH	None of the providers recognized this local name as having a connection. However, the network is not available for at least one provider to whom the connection may belong.

The function returns error codes for compatibility with Windows version 3.1. For compatibility with the Win32 API, the function also sets the error code value returned by GetLastError.
