* Name: sim_zoneinfo
|
|
*
|
|
* Description:
|
|
* Mount the TZ database. The nuttx/zoneinfo directory contains
|
|
* logic to create a version of the TZ/Olson database.
|
|
* This database is required if localtime() support is selected via
|
|
* CONFIG_LIBC_LOCALTIME. This logic in that directory does the following:
|
|
*
|
|
* - It downloads the current TZ database from the IANA website
|
|
* - It downloads the current timezone tools from the same location
|
|
* - It builds the tools and constructs the binary TZ database
|
|
* - It will then, optionally, build a ROMFS filesystem image containing
|
|
* the data base.
|
|
*
|
|
* The ROMFS filesystem image can that be mounted during the boot-up sequence
|
|
* so that it is available for the localtime logic. There are two steps to
|
|
* doing this:
|
|
*
|
|
* - First, a ROM disk device must be created. This is done by calling
|
|
* the function romdisk_register() as described in
|
|
* nuttx/include/nuttx/drivers/ramdisk.h. This is an OS level operation
|
|
* and must be done in the board-level logic before your appliction
|
|
* starts.
|
|
*
|
|
* romdisk_register() will create a block driver at /dev/ramN where N
|
|
* is the device minor number that was provdied to romdisk_regsiter.
|
|
*
|
|
* - The second step is to mount the file system. This step can be
|
|
* performed either in your board configuration logic or by your
|
|
* application using the mount() interface described in
|
|
* nuttx/include/sys/mount.h.
|
|
*
|
|
* These steps, however, must be done very early in initialization,
|
|
* before there is any need for time-related services.
