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.
