FindFirstFile

The FindFirstFile function searches a directory for a file whose name matches the specified filename. FindFirstFile examines subdirectory names as well as filenames.

HANDLE FindFirstFile(

LPCTSTR lpFileName,
// pointer to name of file to search for
LPWIN32_FIND_DATA lpFindFileData
// pointer to returned information
);

Parameters

lpFileName

Windows 95: Points to a null-terminated string that specifies a valid directory or path and filename, which can contain wildcard characters (* and ?). This string must not exceed MAX_PATH characters.

Windows NT: Points to a null-terminated string that specifies a valid directory or path and filename, which can contain wildcard characters (* and ?).

There is a default string size limit for paths of MAX_PATH characters. This limit is related to how the FindFirstFile function parses paths. An application can transcend this limit and send in paths longer than MAX_PATH characters by calling the wide (W) version of FindFirstFile and prepending "\\?\" to the path. The "\\?\" tells the function to turn off path parsing; it lets paths longer than MAX_PATH be used with FindFirstFileW. This also works with UNC names. The "\\?\" is ignored as part of the path. For example, "\\?\C:\myworld\private" is seen as "C:\myworld\private", and "\\?\UNC\bill_g_1\hotstuff\coolapps" is seen as "\\bill_g_1\hotstuff\coolapps".

lpFindFileData

Points to the WIN32_FIND_DATA structure that receives information about the found file or subdirectory. The structure can be used in subsequent calls to the FindNextFile or FindClose function to refer to the file or subdirectory.

Return Values

If the function succeeds, the return value is a search handle used in a subsequent call to FindNextFile or FindClose.

If the function fails, the return value is INVALID_HANDLE_VALUE. To get extended error information, call GetLastError.

Remarks

The FindFirstFile function opens a search handle and returns information about the first file whose name matches the specified pattern. Once the search handle is established, you can use the FindNextFile function to search for other files that match the same pattern. When the search handle is no longer needed, close it by using the FindClose function.

This function searches for files by name only; it cannot be used for attribute-based searches.
