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

Subject: waiting for help about to
understanding the wap/wsp/wtp/wtls sourcecodes
.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...
