* include/hbdyn.ch
* src/rtl/hbdyn.c
+ Added support for misc 'options'. Both for return values
and parameters.
+ Added HB_DYN_OPT_NULLTERM option which will cause that
buffers passed by reference will return null terminated
string (thus cutting the rest of the buffer).
% Implemented macros sent to the list by Przemek. This made
the source significantly smaller (one quarter of original
size) and much easier to manage/modify. Thanks!
* tests/testdyn.prg
+ Added test for zero terminated strings.
! Fixed to set UTF16 mode for Windows "WIDE" call.
* contrib/xpp/dllx.c
% Minor optimization.
