Converts the environment key value pairs to a valid environment string of the form key = value / 0key2 = value2 / 0 / 0 with nulls between each entry and a double null terminator .
// If no dictionary was set, or its empty, the debugger wants null for its environment block. // Collect all the variables as a null delimited list of key=value pairs. // Add a final list-terminating null character. // This is sent to native code as a BSTR and no null is added automatically. // But the contract of the format of the data requires that this be a null-delimited, // null-terminated list.
