Hi,
I'm working on a jsonrpc (client) module that we would like
to make async, using t_suspend and t_continue from the tm
module. I have a couple questions related to this.
The way I understand these functions, t_suspend will freeze
the transaction in shared memory and immediately return and
t_continue will unfreeze the transaction. What I'm not clear on
here is whether t_continue will continue processing of the
transaction within the process that calls t_continue, or will it
delegate to a worker process?
I assume I should spawn an io process in child_init which
will be responsible for sending/receiving on the socket(s), but
what is the best way to communicate between processes? Is there
a way to get a fd from fork_process (that can be written to by
any child and read from using select() in the io thread)?
This is my first attempt at a real module, so any pointers
are greatly appreciated.
Regards,
Matthew WIlliams
