Re: [Opalvoip-devel] [h323plus] More background on changing BOOL to bool

[Quan, R. <rq...@av...>]

I support to move PTLIB to closer to C++ standard and take advantage of
existed libraries. During the transition, the backward compatibility
should be taken care, but it will not be a barrier to stop the
transition.=20

Subject: [h323plus] More background on changing BOOL to bool

To all,

    Here is some background information on the proposed change of BOOL=20
to bool.

    We're trying to move PTLib closer to the C++ standard, including=20
STL, because that has many advantages. Not only will it reduce the size=20
of the code, and increases compatibility with other libraries, but it=20
will leverage off the enormous investment that other developers have=20
made into the standard libraries and will increase the usefulness of=20
PTLib by making the API less "proprietary"

    To do this, PTLib will require several changes. None of these will=20
come without pain, but it is my personal opinion that the advantages=20
will outweigh the disadvantages. These changes are:

    - Change BOOL to bool
    - Change PString to use std::string in some way
    - Change PArray to use std::vector, PDictionary to use std::map etc

   The change from BOOL to bool is probably the biggest change. We're=20
hoping that the rest of the changes can be done transparently, but I=20
think it is inevitable that there will be some API tweaks required.

   I'd be interested in hearing people's opinions on these thoughts,=20
especially if the general consensus is that it is not worthwhile.
