Hi,
I have a question about how to use pool in threads.
I have a main which reads a file and fills an array with about 160000
structs.
Then the mian starts NTHREADS threads with the main pool of main:
apr_thread_create(&tptr[i]->thread_tid, NULL, thread_main,
(void*)context, context)
Each thread is an infinite loop:
..............
for ( ; ; ) {
apr_pool_t *subpool;
if (apr_pool_create(&subpool, context) != APR_SUCCESS) {
return;
}
apr_pool_clear(subpool);
apr_thread_mutex_lock(lock);
<read_an_entry_of_array_and_elaborates_it>
apr_thread_mutex_unlock(lock);
apr_pool_destroy(subpool);
}
A the end the last thread does apr_thread_cond_signal(lock_cond) where
the main is locked.
I'd like to know:
1) Is it the right way to use subpool for a multi-threading programme?
2) In the way I'm using threads after about 200 lines I have a
segmentation fault. So I suppose that there is someting wrong: any advice?
Best regards
Marco
