From CVI's  ActiveX library:

Converts the BSTR string in the variant you specify into a dynamically allocated C-style string.

On success, CA_VariantGetCString releases the contents of the variant and marks it as empty.

CA_VariantGetCString returns an error if the variant does not contain a BSTR value.

When you no longer need the C-style string, call CA_FreeMemory to free it.

Prototype

HRESULT CA_VariantGetCString (VARIANT *Variant, char **Value);
