Microsoft DirectX 8.1 (C++)

FreeBSTR

Frees a task-allocated BSTR string from memory.

Syntax

STDAPI FreeBSTR(
    BSTR *pstr
);

Parameters

pstr

Pointer to the BSTR to free.

Return Value

Returns S_OK if successful, or S_FALSE if pstr is null.

Remarks

Memory is allocated for passing between objects across interfaces by calling CoTaskMemAlloc. It is freed by calling CoTaskMemFree. You can allocate, pass, and free memory safely between objects created in different programming languages by using a central memory allocator.
