I use libwww(ver.4) with some GUI building software. In this software,
a specific event loop runs. I can extend the software by only making a
function of C language that is called when an GUI event arises. So, I
want to use PUT and POST method in preemtive mode.

Then, as a prototype, I modified the HTLine.c file in the ComLine
archive. The difference (Unix diff command) between the original
HTLine.c and my modified one is as follows,

----------8<----------8<----------8<----------8<----------8<----------
477a478,479
>     HTRequest_setPreemtive (cl->request, YES);
> 
493c495
<     HTEvent_Loop(cl->request);
---
> /*    HTEvent_Loop(cl->request);*/
----------8<----------8<----------8<----------8<----------8<----------

If I execute the modified comline(w3c) with -post option, it occurs an
error and core dumped.
And, that with -head option returns nothing.
That with -get option seems to do well.

Thank you.
