# symbol files for libvirt.so

# Build our version script.  This is composed of three parts:
#
# 1. libvirt_public.syms - public API.  These functions are always
# present in the library and should never change incompatibly.
#
# 2. libvirt_private.syms - private API.  These symbols are private and
# semantics may change on every release, hence the version number is
# spliced in at build time. This ensures that if libvirtd, virsh, or a
# driver module was built against one libvirt release, it will refuse to
# load with another where symbols may have same names but different
# semantics. Such symbols should never be visible in an (installed)
# public header file.
#
# 3. libvirt_*.syms - dynamic private API.  Like libvirt_private.syms,
# except that build options (such as --enable-debug) can mean these
# symbols aren't present at all.
