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

ERRORS

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