The MsiCloseAllHandles function closes all open installation handles allocated by the current thread. This is a diagnostic function and should not be used for cleanup.

Syntax

C++UINT MsiCloseAllHandles(void);

Parameters

Return Value

This function returns 0 if all handles are closed. Otherwise, the function returns the number of handles open prior to its call.

Remarks

MsiCloseAllHandles only closes handles allocated by the calling thread, and does not affect handles allocated by other threads, such as the install handle passed to custom actions.

The MsiOpenPackage function opens a handle to a package and the MsiOpenProduct function opens a handle to a product. These function are for use with functions that access the product database.
