NAME

       snmpa_conf - Utility functions for handling the agent config files.

DESCRIPTION

       The  module  snmpa_conf  contains  various  utility  functions  to  used  for manipulating
       (write/append/read) the config files of the SNMP agent.

DATA TYPES

       transportDomain() = transportDomainUdpIpv4 | transportDomainUdpIpv6
       transportAddressIPv4() = [integer()], length 4
       transportAddressIPv6() = [integer()], length 8
       transportAddressMask() = [integer()], length 0 (default), 6 (IPv4) or 10 (IPv6)

EXPORTS
