# Symbols defined in the library which aren't specifically bound to a
# version node are effectively bound to an unspecified base version of
# the library. It is possible to bind all otherwise unspecified symbols
# to a given version node using `global: *' somewhere in the version script.
#
# The interfaces at the "v1" level.
# At this level we present these functions to the linker (and thus to an
# application).
# Any functions not defined in the global list (i.e. "local") will be internal
# to the library (i.e. not exported but used within the library).
# Thus the real function names, "numa_bind_v1" etc, are local and won't
# be known to the linker.

# the first 16 have v1 aliases
# 3 of the 5 system calls that libnuma provides are common to all versions:
