Logical Volume Subroutines

Can some body suggest a work around for LVM routines on Linux.
LVM routines maintains the logical and physical volumes of a volume
group. They are used by the system management commands to perform
system management for the logical and physical volumes of a system. The
programming interface for the library of LVM subroutines is available
to anyone who wishes to provide alternatives to or expand the function
of the system management commands for logical volumes. Basically These
subroutines are from AIXLibrary.
The following services are available:
lvm_querylv Queries a logical volume and returns all pertinent
information.
lvm_querypv Queries a physical volume and returns all pertinent
information.
lvm_queryvg Queries a volume group and returns pertinent information.
lvm_queryvgs Queries the volume groups of the system and returns
information for groups that are varied on-line.

Any work around or Library available on Linux to port these
four routines.

Thanks

The same information is available in the LVM part of
the /proc filesystem: /proc/lvm/*. Open the relevant
file and read the data.
