SetOaNoCache function

Disables the BSTR caching in OleAut32.dll.

Syntax

void __cdecl SetOaNoCache(void);

Parameters

This function has no parameters.

Return value

This function does not return a value.

Remarks

OLE Automation caches the space allocated for BSTR strings. The SetOaNoCache function immediately disables the oleaut32.dll BSTR caching mechanism. All further allocations and deallocations are passed directly to the process allocator. Cached BSTR values are not released. This function should be called before any BSTR operations take place in the process. BSTR caching can also be disabled at the machine level by setting the environment variable OANOCACHE to 1.
