C++ (Cpp) SysReAllocStringLen Examples

Example #1

File: bstr.cpp Project: mingpen/OpenNT

SysReAllocString(BSTR FAR* pbstr, const OLECHAR FAR* psz)
{
    if(psz == NULL)
    {
      SysFreeString(*pbstr);
      *pbstr = NULL;
      return TRUE;
    }

    return SysReAllocStringLen(pbstr, psz, STRLEN(psz));
}
