Pthread thread, look at the help, thank you! ! ! I want to accomplish the following functions : Lane, in the main thread to read the data in the database. Then allocated to the sub-thread to handle, thread handling data deleted from the database, Thread the main thread can control the volume reached a certain number after waiting until a new resurgence after the thread from the thread. I realize the code is structured as follows : While (1) { //read Data 4003rd data distribution Pthread_create (thread, null, p, null); } Void * p (void *) { For (int i = 0; i< sum; i++)    { 4003rd data processing and other functions Call } } In this code mode, the thread is not to handle private data, I used the thread private data, but how are wrong, sometimes core swaps, to help you look at the trouble, then how to handle such requests? Thank you! ! ! [ Closed window ]
