Subject: rb_thread_blocking_region documentation?

Hi,

I am working on  making our Ruby-C extension support Ruby-1.9's
rb_thread_blocking_region feature to have the lock released while
doing a long time consuming operation. Could anybody point me to some
documentation or some links where I will be able to get more details
on the parameters this method is expecting and also the type signature
of parameters the unblock function is expecting.

I went through this link of mail thread where Sasada has replied
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/10252 This
mail thread is old and also in this the rb_thread_blocking_region
method's signature expects only 3 parameters, however when this is
implemented and compiled it throws any arguments mismatch error.
Further googling I found that it expects 4 parameters. Also this link
says the type of parameter the unblocking fucntion expects is
rb_thread_t * , so who will be passing this thread reference. Could
somebody help me out in knowing what is the type signature of the
parameters that the function is expecting.

Help highly appreciated!

Thanks

Praveen
