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



NAME
       epoll_create - open an epoll file descriptor

SYNOPSIS
       #include <&lt;sys/epoll.h>&gt;

       int epoll_create(int size);

DESCRIPTION
       Open  an  epoll file descriptor by requesting the kernel to allocate an
       event backing store dimensioned for size descriptors.  The size is  not
       the  maximum  size  of  the backing store but just a hint to the kernel
       about how to dimension internal structures.  The returned file descrip-
       tor  will  be used for all the subsequent calls to the epoll interface.
       The file descriptor returned by epoll_create() must be closed by  using
       close(2).

RETURN VALUE
       When  successful, epoll_create() returns a non-negative integer identi-
       fying the descriptor.  When an error occurs, epoll_create() returns  -1
       and errno is set appropriately.

ERRORS
       EINVAL size is not positive.

       ENFILE The  system  limit  on  the  total number of open files has been
              reached.

       ENOMEM There was insufficient memory to create the kernel object.

CONFORMING TO
       epoll_create() is Linux-specific, and was introduced in kernel 2.5.44.

NOTES
       Since Linux 2.6.8, the size argument is unused.
