Fork in Linux thread cannot clear zombie process.

Source: Internet
Author: User

In some thread libraries, child processes created by fork in a thread cannot be scavenged by wait or waitpid because of the sig_chld signal that is masked in the thread.

The thread main function can be added to the following code to resolve:

Signal (SIGCLD, sig_ign); /* don ' t need to wait for child process */

The effect of ignoring this signal is to tell the system not to care about the execution return value of the child process, and the system can automatically reclaim all the finished child processes.
