NAMEinotify_init, inotify_init1 - initialize an inotify instance
SYNOPSIS#include <sys/inotify.h> int inotify_init(void); int inotify_init1(int flags);
DESCRIPTIONFor 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(). The following values can be bitwise ORed in flags to obtain different behavior: IN_NONBLOCK Set the O_NONBLOCK file status flag on the new open file description. Using this flag saves extra calls to fcntl(2) to achieve the same result. IN_CLOEXEC Set the close-on-exec (FD_CLOEXEC) flag on the new file descriptor. See the description of the O_CLOEXEC flag in open(2) for reasons why this may be use‐ ful.
RETURN VALUEOn success, these system calls return a new file descriptor. On error, -1 is returned, and errno is set to indicate the error.
ERRORSEINVAL (inotify_init1()) An invalid value was specified in flags. EMFILE The user limit on the total number of inotify instances has been reached. EMFILE The per-process limit on the number of open file descriptors has been reached. ENFILE The system-wide limit on the total number of open files has been reached. ENOMEM Insufficient kernel memory is available.
VERSIONSinotify_init() first appeared in Linux 2.6.13; library support was added to glibc in ver‐ sion 2.4. inotify_init1() was added in Linux 2.6.27; library support was added to glibc in version 2.9.
CONFORMING TOThese system calls are Linux-specific.
