Hi
Karun,
Global multithreading is intentionally prohibited: most
of public functions declared in TCF header files can be called on main thread
only.
Only few
functions are thread safe, most notable one is post_event() that allows to call
a function on main thread.
However, this does not prevent you from creating
multiple instances of command handlers and connecting to multiple
targets.
TCF APIs are asynchronous and call-back based, which
allows same level of concurrency as multithreading.
Regards,
Eugene

handler with my own which posted tcf commands after reading test cases list. So
you can say it is kind of script. Actually I implemented this on a old version
of tcf which had only command line functionality and no script file handling. So
I made my own handler for reading my test case list and launching the test
cases. I hope it is clear
now. Regards, Karun From:

Karun, I'm not
sure I understand your question. What do
you mean by "wrapper around client"? Is it a
script that uses TCF command line client? Or, are
you using TCF API? Which one - C or Java? Regards, Eugene From:

Behalf Of Karun SARASWAT Hi
all, I have developed
my regression test framework for testing linux device drivers with TCF. Process
service is used for launching my target test cases and client running on PC
records the result. I have developed a wrapper around client to parse my test
case files and manage the flow of the test case execution. Now i wish to
extend it further by allowing multiple instances of regression running on
different target ( test case distribution) or multiple instance of
agent on same target. For this i want to run multiple threads of client handler
managing each agent connection. I want to know
if TCF is thread safe if i instantiate multiple instances of client or to
be specific multiple handlers each connecting to different targets? I want
to handle context for each thread differently. I guess for now only
one handler is present which is over written for each connect command. Can we
support multiple handlers by generating unique handler for each connection?
Please correct
me if I have misunderstood anything. Thanks and
regards, Karun |
