Re: [Vala] Genie xmlrpc-c bindings test

[Phil Daintree <phil logicworks co nz>]

Crickey I figured it out!

I changed the xmlrpc.vapi file

to

[CCode (cname="xmlrpc_struct_read_value")]
public void struct_read_value(Value stru, string key, out Value v);

instead of:

[CCode (cprefix="xmlrpc_")]
public void struct_read_value(Value stru, string key, out Value v);

for whatever reason vala was thinking the C library function was called 
xmlrpc_env_struct_read_value - but it is actually called 
xmlrpc_struct_read_value without the _env in there.

The cprefix="xmlrpc_" didn't seem to be working there is an earlier 
cprefix='xmlrpc_env" line above the Env Structure definition:

[CCode (cname ="xmlrpc_env", cprefix="xmlrpc_env_", free_function="", 
destroy_function="xmlrpc_env_clean")]
        public struct Env {

These methods within the Env struct do not seem to be taking the correct 
prefix.

It's my guess that all the struct functions/methods will not work I will 
test out and post a fixed up bindings now I know how to do it.

Sorry to clog the list with stuff that is perhaps not even mainstream 
vala. However, it might help anyone who comes after trying to do similar 
things.

Thanks Jan/Evan/Jamie/Pancake for getting me going with this.
