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.

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.
