Question auto update on directory change

Hi all!

Recently I've started to develop a small program that needs to
check for the arrival of files in a pre-determined directory.

I could use a timer to check for changes in this directory every n seconds.

Instead, what I'm really looking for is for some kind of notification mechanism from the OS. I want the application to register for notifications from the OS for any changes in the directory the application is "listening" for.

Any ideas how I could implement this?

Thanks in advance, regards,
Bruno

NAME
filecap - a program to see capabilities SYNOPSIS
filecap [ -a | -d | /dir | /dir/file [cap1 cap2 ...] ] DESCRIPTION
filecap is a program that prints out a report of programs with file based capabilities. If a file is not in the report or there is no report at all, no capabilities were found. For expedience, the default is to check only the directories in the PATH environmental variable. If the -a command line option is given, then all directories will be checked. If a directory is passed, it will recursively check that directory. If a path to a file is given, it will only check that file. If the path to the file includes capabilities, then they are written to the file. OPTIONS
-a This tells the program to show all capabilities starting from the / directory. Normally the PATH environmental variable is used to show you capabilities on files you are likely to execute. -d This dumps all capabilities for reference. EXAMPLES
To check file capabilities in $PATH: filecap To check file capabilities of whole system: filecap -a To check file capabilities recursively in a directory: filecap /usr To check file capabilities of a specific program: filecap /bin/passwd To list all possible capabilities: filecap -d To set a file capability on a specific program: filecap /bin/ping net_raw net_admin SEE ALSO
