The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.

NAME intro – introduction to system calls DESCRIPTION Section 2 of the manual describes the Linux system calls. A system call is an entry point into the Linux kernel. Usually, system calls are not invoked directly: instead, most system calls have corresponding C library wrapper functions which perform the steps required (e.g., trapping to kernel…

NAME inotify_rm_watch – remove an existing watch from an inotify instance SYNOPSIS #include <sys/inotify.h> int inotify_rm_watch(int fd, int wd); DESCRIPTION inotify_rm_watch() removes the watch associated with the watch descriptor wd from the inotify instance associated with the file descriptor fd. Removing a watch causes an IN_IGNORED event to be generated for this watch descriptor. (See…
NAME inotify_init, inotify_init1 – initialize an inotify instance SYNOPSIS #include <sys/inotify.h> int inotify_init(void); int inotify_init1(int flags); DESCRIPTION For an overview of the inotify API, see inotify(7). inotify_init() initializes a new inotify instance and returns a file descriptor associated with a new inotify event queue. If flags is 0, then inotify_init1() is the same as inotify_init()….
