# To add error code to your module, you need to do the following:
#
# 1) Add a module offset code.  Add yours to the bottom of the list
# right below this comment, adding 1.
#
# 2) In your module, define a header file which uses one of the
# NE_ERROR_GENERATExxxxxx macros.  Some examples below:
#
#    #define NS_ERROR_MYMODULE_MYERROR1 \
#        NS_ERROR_GENERATE(NS_ERROR_SEVERITY_ERROR,NS_ERROR_MODULE_MYMODULE,1)
#    #define NS_ERROR_MYMODULE_MYERROR2 NS_ERROR_GENERATE_SUCCESS(NS_ERROR_MODULE_MYMODULE,2)

#       and then all errors associated with that module become offsets from the
