C++ qFatal函数代码示例

/*!
forks the current Process
you can specify weather it will write a pidfile to /var/run/mydaemon.pid or not
if you specify true (the default) QxtDaemon will also try to lock the pidfile. If it can't get a lock it will assume another daemon of the same name is already running and exit
be aware that after calling this function all file descriptors are invalid. QFile will not detect the change, you have to explicitly close all files before forking.
return true on success
