collectl - http://collectl.sourceforge.net/

collectl has the ability to monitor threads in either top more or rolling output. if these are short-lived, you can always set a monitoring interval to < 1 sec! In fact, if you know the process name and issue the following command:

collectl --top --procfile cxxx --protopt t -i:0.01

it will look for all processes with the string xxx anywhere in their command line as well as any threads with that name once every 0.01 seconds!

pthread_detach(3C)														pthread_detach(3C)

NAME
pthread_detach - detach a thread SYNOPSIS
cc -mt [ flag... ] file... -lpthread [ library... ] #include <pthread.h> int pthread_detach(pthread_t thread); The pthread_detach() function is used to indicate to the implementation that storage for the thread thread can be reclaimed when that thread terminates. In other words, pthread_detach() dynamically resets the detachstate attribute of the thread to PTHREAD_CRE- ATE_DETACHED. After a successful call to this function, it would not be necessary to reclaim the thread using pthread_join(). See pthread_join(3C). If thread has not terminated, pthread_detach() will not cause it to terminate. The effect of multiple pthread_detach() calls on the same target thread is unspecified. If successful, pthread_detach() returns 0. Otherwise, an error number is returned to indicate the error. The pthread_detach() function will fail if: EINVAL The implementation has detected that the value specified by thread does not refer to a joinable thread. ESRCH No thread could be found corresponding to that specified by the given thread ID.
