Re: adding mibs to agent

hi Dave ,
 here only ,i came across the term MIB API

MIB API (Application Interface): This is system specific code required
to satisfy the requirements of MIB-II and other MIB's as those are
added to the system. For example, in order to retrieve the object
sysUpTime, SNMP looks for an API function called GetTimeTicks in the
MIB API library provided by the host-system. In the section on
"Implementing MIB-II objects" we detail how to implement the API
module to fulfill the requirements of MIB-II objects. API modules for
additional MIB's are specific to the MIB application; however, the
section on "Adding Additional MIB's" provides examples of such API
modules.
