Retrieves attributes for a specified file or directory.
To perform this operation as a transacted operation, use the GetFileAttributesTransacted function.
BOOL GetFileAttributesExA( LPCSTR lpFileName, GET_FILEEX_INFO_LEVELS fInfoLevelId, LPVOID lpFileInformation );
The name of the file or directory.
In the ANSI version of this function, the name is limited to MAX_PATH characters. To extend this limit to 32,767 wide characters, call the Unicode version of the function (GetFileAttributesExW), and prepend "\?" to the path. For more information, see Naming a File.
A class of attribute information to retrieve.
This parameter can be the following value from the GET_FILEEX_INFO_LEVELS enumeration.
||The lpFileInformation parameter is a WIN32_FILE_ATTRIBUTE_DATA structure.|
A pointer to a buffer that receives the attribute information.
The type of attribute information that is stored into this buffer is determined by the value of fInfoLevelId.
If the function succeeds, the return value is a nonzero value.
If the function fails, the return value is zero (0). To get extended error information, call GetLastError.
The GetFileAttributes function retrieves file system attribute information. GetFileAttributesEx can obtain other sets of file or directory attribute information. Currently, GetFileAttributesEx retrieves a set of standard attributes that is a superset of the file system attribute information.
When the GetFileAttributesEx function is called on a directory that is a mounted folder, it returns the attributes of the directory, not those of the root directory in the volume that the mounted folder associates with the directory. To obtain the attributes of the associated volume, call GetVolumeNameForVolumeMountPoint to obtain the name of the associated volume. Then use the resulting name in a call to GetFileAttributesEx. The results are the attributes of the root directory on the associated volume.
