Converts a `BSTR` value to a `char *`.

## Syntax

```
char* __stdcall ConvertBSTRToString(BSTR pSrc);
```

#### Parameters

A BSTR variable.

## Remarks

**ConvertBSTRToString** allocates a string you must delete.

## Example

```cpp
// ConvertBSTRToString.cpp
#include <comutil.h>
#include <stdio.h>

#pragma comment(lib, "comsuppw.lib")

int main() {
   BSTR bstrText = ::SysAllocString(L"Test");
   wprintf_s(L"BSTR text: %s\n", bstrText);

   char* lpszText2 = _com_util::ConvertBSTRToString(bstrText);
   printf_s("char * text: %s\n", lpszText2);

   SysFreeString(bstrText);
   delete[] lpszText2;
}
```
