[scsoce]

A child thread has a long-time executions, how to suspend it and resume
back the orignial place ?
I know it' nature to use singal, but child thread cannot get signal as
Python Manual say. And i dnt like to check status variable as the
long-time executions can not or be dirty to stop to do check.

Hello,

A child thread has a long-time executions, how to suspend it and resume
back the orignial place ?

I don't think you can do it using Python's thread API.
You can either use a platform specific API (such as pywin32) or make
the thread "cooperative" and wait on a condition/semaphore in some
inner loop.

I know it' nature to use singal, but  child thread cannot get signal as
Python Manual say.  And i dnt like to  check status variable  as the
long-time executions can not or be dirty to stop to do check.

Threads and signals don't play well together. Not recommended.

HTH,
