NAME
inotifyinit, inotifyinit1 - initialize an inotify instance SYNOPSIS
#include
int inotifyinit(void); int inotifyinit1(int flags); DESCRIPTION inotifyinit() initializes a new inotify instance and returns a file descriptor associated with a new inotify event queue. If flags is 0, then inotifyinit1() is the same as inotifyinit(). The following values can be bitwise ORed in flags to obtain different behavior: INNONBLOCK Set the ONONBLOCK file status flag on the new open file description. Using this flag saves extra calls to fcntl(2) to achieve the same result. INCLOEXEC Set the close-on-exec (FDCLOEXEC) flag on the new file descriptor. See the description of the OCLOEXEC flag in open(2) for reasons why this may be useful. RETURN VALUE On success, these system calls return a new file descriptor. On error,
-1 is returned, and errno is set to indicate the error. ERRORS EINVAL (inotifyinit1()) An invalid value was specified in flags. EMFILE The user limit on the total number of inotify instances has been reached. ENFILE The system limit on the total number of file descriptors has been reached. ENOMEM Insufficient kernel memory is available. VERSIONS inotifyinit() first appeared in Linux 2.6.13; library support was added to glibc in version 2.4. inotifyinit1() was added in Linux 2.6.27; library support was added to glibc in version 2.9. CONFORMING TO
These system calls are Linux-specific. SEE ALSO inotifyaddwatch(2), inotifyrmwatch(2), inotify(7) COLOPHON
