# GDB macros for use with Quagga.
#
# Macros in this file are specific to ospfd/. Definitions here depend on the
# lib.txt macros file, which must also be loaed.
#
# The macro file can be loaded with 'source <filename>'. They can then be   
# called by the user. Macros that explore more complicated structs generally
# take pointer arguments.
