[OpenSIPS-Devel] Some questions about opensips...

[徐飞]

Hi Professors：

Recently I have worked with your project opensips, to develop a system. In
this period, I have encountered some problems...

1. How does the project configure file (opensips.cfg) call the functions
which are provided by the project modules. For example, function "save()"
is exported in the module “registerar”, and how can the configure file call
"save("location");". How is it implemented?

2. I have found that the configure file also called the functions which are
not exported in the project modules, such as "setflag()","setbflag()",
"isbflag()", so this time how can the configure file call them? I am a
little confused....and I do need your help....

3. What is the meaning of the data structure "branch" which is defined in
the "dest.c". What is it used for? Does it have the same meaning of the
"branch" in the SIP protocol?

My quesuons is a little stupid...
Looking forward to your help!!
