Special highlights for software construction utilities are presented in the perspective of software development when starting a new project. apr_status_t apr_proc_kill ( apr_proc_t * proc, int sig ) Terminate a process.

This is used to find the process to unregister. As mentioned earlier, if thread is detached, we don't need to call apr_thread_join() for it. apr_status_t apr_threadattr_stacksize_set ( apr_threadattr_t * attr, apr_size_t stacksize ) Set the stack size of newly created threads.

init_threadsThe number of threads to be created initially, this number will also be used as the initial value for the maximum number of idle threads. APR hash tables are used to develop a word frequency counting applications. detachShould the child start in detached state? http://apr.apache.org/docs/apr/1.5/group__apr__thread__proc.html This is how the underlying functions determine if the function has ever been called before.

To create a new thread, we can create a thread attribute object by apr_threadattr_create() if we need it. You can save some extra function calls by not creating your own pipe since this creates one in the process space for you. Parameters attrThe procattr describing the child process to be created. Thread and memory pool is difficult to control properly.

Bug:Note that calling this function with two NULL files on some platforms creates an APR_FULL_BLOCK pipe, but this behavior is neither portable nor is it supported. http://dev.ariel-networks.com/apr/apr-tutorial/html/apr-tutorial-16.html Parameters procThe process to check reasonThe reason code to pass to the maintenance function statusThe status to pass to the maintenance function RemarksAn example of code using this behavior; rv = Generated by 1.8.10 Apache Portable Runtime MainPage RelatedPages Modules DataStructures Files Modules | Data Structures | Macros | Typedefs | Enumerations | Functions Threads and Process FunctionsApache Portability Runtime library void apr_proc_other_child_unregister ( void * data) Stop watching the specified other child.

Parameters meThe thread pool cntThe new threshold ReturnsThe original threshold apr_status_t apr_thread_pool_top ( apr_thread_pool_t * me, apr_thread_start_t func, void * param, apr_byte_t priority, void * owner ) Schedule a task to

write_fdAn fd that is probed for writing.

In case all existing threads are busy and the number of tasks in the queue is higher than the adjustable threshold, the pool will try to create a new thread to Parameters attrThe procattr we care about. The second argument is thread attribute object mentioned above.

Even if it seems that parent thread generates a child thread, they are completely equal, so that we should consider one thread is splitted to two threads. apr_size_t apr_thread_pool_idle_count ( apr_thread_pool_t * me) Get the current number of idle threads Parameters meThe thread pool ReturnsNumber of idle threads apr_size_t apr_thread_pool_idle_max_get ( apr_thread_pool_t * me) Access function for the
