Glad to help. I am quite disturbed about Google ban, as well. Fortunately, 
there are other search engines that you can use. But let's keep it down, I 
wouldn't like to see kannel.org banned as well ;-)

BR,
Nikos

        Hi:
              thanks a lot for your guidance,Nikos ! I think I have understand 
the the principle of the source codes now ! The gcc < -E> is an really 
interesting stuff indeed ! In addition, expressed regret that the google had to 
withdraw from China,most of the Chinese programmers through Google to search 
for solutions to problems, and fuck all the Ignoble politicians！

          Hi,

          I am afraid I don't have the time to show you the ropes... However, I 
can point you to the right direction.

          #defines are preprocessor directives. They wreak havoc with the 
debugger (you cannot step through) and I do not understand them that well 
either. They are mostly legacy and are kept around to preserve compactness and 
style with previous code. Some of them are more functional, by giving a certain 
object-oriented style, or forcing several function prototypes and wrappers.

          You can see what they are doing by using:

          gcc <options> -E > progE.c

          where <options> is the output from the make command for the file you 
are interested in (skipping the -c -o output part). The output progE.c can be 
compiled under kannel like the regular initial file.

          There are plenty of tutorials and how-tos in the web on using the 
preprocessor in C.

          BR,
          Nikos

                  .I have read the protocol specifications doc such as 
wap-wtp-wtls downloaded from the wapforum,and understand how it works,but when 
i am reading the source codes of the wap/wsp/wtp/wtls,i'm very much 
puzzled,because they were defined in a very mysterious or magical way: los of 
struct/enum/union with ( #define/"include...") in them,and also i can not 
understand how the definitions in the *def works,the styles of them looks like 
the overloading functions of C++,but i have never seen such styles in C 
before------.....Can someone teach me how to understand theirs Working 
principle??? thanks a lot...
