MSGOP(2)
NAME
msgrcv, msgsnd - System V message queue operations

EXAMPLE
The program below demonstrates the use of msgsnd() and msgrcv().

Deleting a task from another task's context will not do, so shut
this gate down for BUILD_KERNEL. In this case if a task wants another
task to terminate, it must ask the other task to politely kill itself.
Note: kthreads still need this, also, the kernel can delete a task
without asking.
Now that the environment strings are stored as an array of strings,
they can be passed from the application via char **environ, which
is really defined as a function call to get_environ_ptr().
This works as is for flat build, but protected mode and kernel mode
require a call gate, which is added here.
to fix the following warning:
include/unistd.h:302:9: error: incompatible redeclaration of library function 'vfork' [-Werror,-Wincompatible-library-redeclaration]
pid_t vfork(void);
^
include/unistd.h:302:9: note: 'vfork' is a builtin with type 'int (void)'
and change 32768 to INT_MAX to match the type change

since VNC server is very useful even without NX:
1.Replace nxgl_coord_t with fb_coord_t
2.Replace nxgl_rect_s with fb_area_s
3.Remove nxgl_xxx function call

BOARDIOC_SWITCH_BOOT is required to communicate the boot partition from
userspace (OTA subsystem) to board. It can be used to change the system
boot behavior. So it's useful for A/B boot or even single boot case.
For the board support A/B boot case:
1. Download the new image from the sever
2. Write the new image to the alternative partition
3. Call BOARDCTL_SWITCH_BOOT to the alternative system
For single boot partition case:
1. Download the new image from the sever
2. Call BOARDCTL_SWITCH_BOOT and reboot to a small system
3. Write the new image to the main partition in the small system
4. Call BOARDCTL_SWITCH_BOOT again to the main system
