SetCurrentDirectory

切換當前進程的當前工作目錄。

BOOL WINAPI SetCurrentDirectory( __in LPCTSTR lpPathName);

lpPathName [in]

The path to the new current directory. This parameter may specify a relative path or a full path. In either case, the full path of the specified directory is calculated and stored as the current directory. For more information, see File Names, Paths, and Namespaces.

The string must not exceed MAX_PATH characters, including the terminating null character. The final character before the null character must be a backslash ('\'). If you do not specify the backslash, it will be added for you; therefore, specify MAX_PATH-2 characters for the path unless you include the trailing backslash, in which case, specify MAX_PATH-1 characters for the path.

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.

Each process has a single current directory made up of two parts:

A disk designator that is either a drive letter followed by a colon, or a server name and share name (\\servername\sharename)A directory on the disk designator
