feature_test_macros – feature test macros Description Feature test macros allow the programmer to control the definitions that are exposed by system header files when a program is compiled. NOTE: In order to be effective, a feature test macro must be defined before including any header files. This can be done either in the compilation command…
fanotify – monitoring filesystem events Description The fanotify API provides notification and interception of filesystem events. Use cases include virus scanning and hierarchical storage management. In the original fanotify API, only a limited set of events was supported. In particular, there was no support for create, delete, and move events. The support for those events…
