Introduzione
FAM monitors files and directories, notifying interested applications of
changes. More information about FAM is available at
http://oss.sgi.com/projects/fam/.
A PHP script may specify a list of files for FAM to monitor
using the functions provided by this extension.
The FAM process is started when the first connection
from any application to it is opened. It exits after all
connections to it have been closed.
