Size of LVM header in non bootable disk

i have a query regarding the size of the LVM header. Since the LVM header of a bootable disk is always 2912KB. The header size of a non bootable disk is not fixed. In Bootable disk after the LVM header (2912 KB=5824 sectors)the user data starts or we can say LV extents starts.
If i extend any Logical volume from bootable disk to my 2nd hdd of the same VG. suppose i increase the size of /home LV 2GB to 5GB and it extended on the new hdd which i attatched on my machine.

If on PV1 512 PE(4MB) resides and remaining PE resides on 2nd hdd.
How i can trverse on the 2nd hdd from where my 513th extent start?
I am developing a C++ module that for this.
Please guide me how i can get this information.

pvck - check physical volume metadata SYNOPSIS
pvck [-d|--debug] [-h|--help] [-v|--verbose] [--labelsector] PhysicalVolume [PhysicalVolume...] DESCRIPTION
pvck checks physical volume LVM metadata for consistency. OPTIONS
See lvm for common options. --labelsector sector By default, 4 sectors of PhysicalVolume are scanned for an LVM label, starting at sector 0. This parameter allows you to specify a different starting sector for the scan and is useful for recovery situations. For example, suppose the partition table is corrupted or lost on /dev/sda, but you suspect there was an LVM partition at approximately 100 MB. This area of the disk may be scanned by using the --labelsector parameter with a value of 204800 (100 * 1024 * 1024 / 512 = 204800): pvck --labelsector 204800 /dev/sda Note that a script can be used with --labelsector to automate the process of finding LVM labels.
