Initializes security attributes with a DACL restricted to the current process user.

The resulting DACL grants GENERIC_ALL access to the calling user only, so the created object cannot be opened, signaled or otherwise accessed by other users on the system. The allocated DACL must be released with free_security_attributes() once the security attributes are no longer needed.

Parameters

obj	Security attributes structure to initialize.

Returns: true on success, false otherwise.
