Question
I have char* array and I am dynamically allocating memory for it.
char *strData = new char[length+1];
This char* I am passing to _bstr_t as below,
_bstr_t bstrData = strData;
How to free up the memory allocated for the char* through bstrData ?
Solution
_bstr_t
manages its own internal buffer (created by SysAllocString). So once you create the _bstr_t
, it's safe to delete the char array you've allocated. bstrData
will still be absolutely useful.
