void ast_replace_sigchld | ( | void | ) |
Replace the SIGCHLD handler.
Normally, Asterisk has a SIGCHLD handler that is cleaning up all zombie processes from forking elsewhere in Asterisk. However, if you want to wait*() on the process to retrieve information about it's exit status, then this signal handler needs to be temporarily replaced.
Code that executes this function must call ast_unreplace_sigchld() after it is finished doing the wait*().

int ast_safe_execvp | ( | int | dualfork, |

Safely spawn an external program while closing file descriptors.
dualfork | Non-zero to simulate running the program in the background by forking twice. The option provides similar functionality to the '&' in the OS shell command "cmd &". The option allows Asterisk to run a reaper loop to watch the first fork which immediately exits after spaning the second fork. The actual program is run in the second fork. |
