DNS library and multi-process

Hello,

I use C with keil compiler

I am doing various TCP requests and I am using DNS library, all this at 
the same time using task scheduler library.
I know that I mustn't call the same DNS function twice at the same time 
and I don't do this. But this library seems to badly support the 
presence of other threads runing at the same time.

The application behaves strangely (often failing the DNS request), and 
generally ends by hanging or rebooting. Removing the call to the 
gethostbyname() function seems to solve the problems.

I know there are some problems with keil function which are not 
reentrant at all, so -- as suggested in a thread on this mailing list -- 
each call to these functions is surrounded with a 
task_entercritsection() / task_leavecritsection() in my code.

My question is do you use internaly in the DNS library any keil function 
(like strlen(), ...) which could cause my problems ?
Any other idea ?

Thanks for your help

					Xavier
