/* with this source file a new experimental approach is being introduced:
|
|
normally when adding a new option at least four existing files have to be
|
|
adapted; this is similar for new address types.
|
|
|
|
in the future i would like to have a more automatic assembling of socat from
|
|
topic oriented source files. this should make integration and control of
|
|
contributions more easy.
|
|
|
|
all code of a new topic - address and option definitions, open code, option
|
|
handing code, ev.parser code, etc. should go into one source file. the
|
|
selection of the desired code parts during the compilation is done by
|
|
setting cpp defines.
|
|
|
|
in the same was all public declarations should go in one header (.h) file.

ENABLE_APPLYOPTS: C code that applies the address option passed in opt
