Hi

Is there a similar method like Marshal::StringToHGlobalAnsi() by using an
existing pointer, rather than allocating memory and returning a new pointer?
My target buffers are persistent must must not be allocated every time when
converting from String to char*;

Thanks,
Urs

You can use "WideCharToMultiByte" in conjuction with "PtrToStringChars".
