Re: [Freeswitch-users] Fork( ) and Exec ( ) functions

Usually fork-less OSes provide spawn() family of syscalls to execute a new process. On Sunday 18 January 2015 20:32:02 Abdul Hakeem wrote:

You can also look at how we have addressed this issue for windows. The places I know of that use these functions. switch_system (used for executing external commands and sending emails), and daemonizing FreeSWITCH.

We use threads by default in the switch system. There is a setting to use fork instead but it's disabled by default. The system syscall uses fork and exec on its own so maybe you just need to make sure ifdefs properly disable any such functionality.

most likely this is going to require you to make code changes, not just makefile changes.
