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



NAME
       epoll_create - open an epoll file descriptor

SYNOPSIS
       #include <sys/epoll.h>

       int epoll_create(int size)

DESCRIPTION
       Open  an  epoll  file descriptor by requesting the kernel 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 struc-
       tures.  The returned file descriptor will be used for all the subsequent  calls  to
       the epoll interface. The file descriptor returned by epoll_create(2) must be closed
       by using close(2).

RETURN VALUE
       When  successful,  epoll_create(2)  returns  a  positive  integer  identifying  the
       descriptor.   When  an  error  occurs,  epoll_create(2) returns -1 and errno is set
       appropriately.

ERRORS
       ENOMEM There was insufficient memory to create the kernel object.

CONFORMING TO
       epoll_create(2) is a new API introduced in  Linux  kernel  2.5.44.   The  interface
       should be finalized by Linux kernel 2.5.66.
