INOTIFY_RM_WATCH(2) Linux Programmer's Manual INOTIFY_RM_WATCH(2)

inotify_rm_watch - remove an existing watch from an inotify instance

#include <sys/inotify.h>
int inotify_rm_watch(int fd, int wd);

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 inotify(7).)

On success, inotify_rm_watch() returns zero. On error, -1 is returned and errno is set to indicate the cause of the error.

fd is not a valid file descriptor.
The watch descriptor wd is not valid; or fd is not an inotify file descriptor.

Inotify was merged into the 2.6.13 Linux kernel.

This system call is Linux-specific.
