CORBA IDL to C++ - char vs. unsigned char?

We're using OmniORB with our C++ server. Currently, when an object is specified as a char in the IDL file, it is translated to an unsigned char in C++. We want it to be just char. Is there something we can change to make this happen?

Solution

  • It is implementation defined (page 15 in the spec) what the IDL types boolean, char and octet map to.

    omniORB chooses to:

    ...
typedef unsigned char _CORBA_Char;
typedef unsigned char _CORBA_Octet; 
...

    You can change the omniORB sources, though I doubt that would be a good idea. Or you can accept that CORBA::Char does not represent the C++ char type.
