Hello once again,
Just wondering about pthreads now. I know that the lifetime (scope)
of a regular procedural function in C is simple.. it's from the top of
the function body to the bottom of the function body (assuming no
infinite loops are injected). Example:
(void*) function(void*) {/* lifetime of function is here. */ }
However looking over pthread(3), there are a number of different
functions for killing threads and exiting child threads, in order
terminate child threads (and maybe to get back to the main thread of
execution in a program).
So my question is, once the end of a function body is reached that was
made using pthread_create(), does the thread exit and 'destroy' itself
or do I need to do 'manual' cleanup, i.e. run pthread_detach(3),
pthread_exit(3), or pthread_kill(3)?
Thanks!
