_WinAPI_DecryptFile

Decrypts an encrypted file or directory.

#Include <WinAPIEx.au3>
_WinAPI_DecryptFile ( $sFile )

参数

$sFile The name of the file or directory to be decrypted. If $sFile specifies a read-only file, the function
fails and the last error code is ERROR_FILE_READ_ONLY (6009). If $sFile specifies a directory that
contains a read-only file, the functions succeeds but the directory is not decrypted.

返回值

成功: 返回 1.
失败: 返回 0 并设置 @error 标志为非 0 值.

注意/说明

The _WinAPI_DecryptFile() function requires exclusive access to the file being decrypted, and will fail
if another process is using the file.

If the file is not encrypted, the function simply returns a nonzero value, which indicates success.
