Linux Programmer's Manual
NAME
epoll_create, epoll_create1 - open an epoll file descriptor
...
SYNOPSIS
#include <sys/epoll.h>
int epoll_create1(int flags);
...
epoll_create1()
If flags is 0, then, other than the fact that the obsolete
size argument is dropped, epoll_create1() is the same as
epoll_create(). The following value can be included in flags
to obtain different behavior:
EPOLL_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 useful.

DESCRIPTION
EPOLL_CTL_DEL
...
The event argument describes the object linked to the file descriptor
fd. The struct epoll_event is defined as:
typedef union epoll_data {
void *ptr;
int fd;
uint32_t u32;
uint64_t u64;
} epoll_data_t;
struct epoll_event {
uint32_t events; /* Epoll events */
epoll_data_t data; /* User data variable */
};

Provide functions which get and set the 3A (Auto white balance/Auto
exposure/Auto
focus) parameters.
These are achieved by the ioctl request codes VIDIOC_G_EXT_CTRLS and
VIDIOC_S_EXT_CTRLS which have the following settings:
1. ctrl_class = V4L2_CTRL_CLASS_CAMERA
2. id = V4L2_CID_3A_PARAMETER
Also, provide function which get the 3A adjustment status.
This is achieved by the ioctl request codes VIDIOC_G_EXT_CTRLS which has the
following settings:
1. ctrl_class = V4L2_CTRL_CLASS_CAMERA
2. id = V4L2_CID_3A_STATUS
Fix the following three bugs about ON/OFF control of auto white balance and auto
exposure:
- The returned value of VIDIOC_G_CTRL with id = V4L2_CID_AUTO_WHITE_BALANCE is
different from V4L2 specification.
- Auto exposure is locked if auto white balance lock is requested.
- Auto exposure and auto white balance are locked if auto exposure lock is
requested.

Add flags argument into sendto() and recvfrom() APIs for MSG_* flags can
handling in the daemon.
However, MSG_DONTWAIT should process in usrsock, so it unnecessary to pass to
the daemon like O_NONBLOCK.

yes, symlink is different from link:
1.symlink create the soft(symbolic) link
2.link create the hard link
but it is suitable to make them same now since vfs doesn't support the
hard link and the soft link in file system level yet.

mallinfo is meant to be API compatible with Linux,
where it's provided by malloc.h.
Make stdlib.h include malloc.h for now. It can be removed
once all users are updated to include malloc.h instead of
stdlib.h.
I have some app code which uses mallinfo(). I want to share
it between platforms. This commit allows me to reduce
platform-ifdefs.
(I think the API actually originated with System V. I don't
remember how it was there though. Anyway, I guess the
compatibility with Linux is more important than System V
these days.)
The video stream driver must be intialized from the board to comply with NuttX
NOTE:
Please remove the initalization from any camera example
