    DESCRIPTION

    The SSAAgentIsAlive() function returns TRUE if the master agent is alive, otherwise returns FALSE. The agent_addr parameter is the address of the agent. Specify the security token in the community parameter. You can specify the maximum amount of time to wait for a response with the timeout parameter.

    The SSAGetTrapPort() function returns the port number used by the Master Agent to communicate with the subagent.

    The SSARegSubagent() function enables a subagent to register and unregister with a Master Agent. The agent parameter is a pointer to an Agent structure containing the following members:

    int      timeout;         /* optional */ 
    int      agent_id;        /* required */ 
    int      agent_status;    /* required */ 
    char     *personal_file;  /* optional */ 
    char     *config_file;    /* optional */ 
    char     *executable;     /* optional */ 
    char     *version_string; /* optional */
    char     *protocol;       /* optional */ 
    int      process_id;      /* optional */ 
    char     *name;           /* optional */ 
    int      system_up_time;  /* optional */ 
    int      watch_dog_time;  /* optional */ 
    Address  address;         /* required */ 
    struct   _Agent;          /* reserved */ 
    struct   _Subtree;        /* reserved */
    

    The agent_id member is an integer value returned by the SSASubagentOpen() function. After calling SSASubagentOpen(), you pass the agent_id in the SSARegSubagent() call to register the subagent with the Master Agent.

    The following values are supported for agent_status:

    SSA_OPER_STATUS_ACTIVE 
    SSA_OPER_STATUS_NOT_IN_SERVICE 
    SSA_OPER_STATUS_DESTROY 
    

    You pass SSA_OPER_STATUS_DESTROY as the value in a SSARegSubagent() function call when you want to unregister the agent from the Master Agent.

    Address has the same structure as sockaddr_in, that is a common UNIX structure containing the following members:

    short      sin_family;
    ushort_t   sin_port;
    struct     in_addr sin_addr;
    char       sin_zero[8];
    

    The SSARegSubtable() function registers a MIB table with the Master Agent. If this function is successful, an index number is returned, otherwise 0 is returned. The table parameter is a pointer to a SSA_Table structure containing the following members:

    int  regTblIndex;         /* index value */
    int  regTblAgentID;       /* current agent ID */
    Oid  regTblOID;           /* Object ID of the table */
    int  regTblStartColumn;   /* start column index */
    int  regTblEndColumn;     /* end column index */
    int  regTblStartRow;      /* start row index */
    int  regTblEndRow;        /* end row index */
    int  regTblStatus;        /* status */
    

    The regTblStatus can have one of the following values:

    SSA_OPER_STATUS_ACTIVE 
    SSA_OPER_STATUS_NOT_IN_SERVICE 
    

    The SSARegSubtree() function registers a MIB subtree with the master agent. If successful this function returns an index number, otherwise 0 is returned. The subtree parameter is a pointer to a SSA_Subtree structure containing the following members:

    int  regTreeIndex;      /* index value */
    int  regTreeAgentID;    /* current agent ID */
    Oid  name;              /* Object ID to register */
    int  regtreeStatus;     /* status */
    

    The regtreeStatus can have one of the following values:

    SSA_OPER_STATUS_ACTIVE 
    SSA_OPER_STATUS_NOT_IN_SERVICE 
    

    The SSASendTrap() function instructs the Master Agent to send a trap notification, based on the keyword passed with name. When your subagent MIB is compiled by mibcodegen, it creates a lookup table of the trap notifications defined in the MIB. By passing the name of the trap notification type as name, the subagent instructs the Master Agent to construct the type of trap defined in the MIB.

    The SSASubagentOpen() function initializes communication between the subagent and the Master Agent. You must call this function before calling SSARegSubagent() to register the subagent with the Master Agent. The SSASubagentOpen() function returns a unique agent ID that is passed in the SSARegSubagent() call to register the subagent. If 0 is returned as the agent ID, the attempt to initialize communication with the Master Agent was unsuccessful. Since UDP is used to initialize communication with the Master Agent, you may want to set the value of num_of_retry to make multiple attempts.

    The value for agent_name must be unique within the domain for which the Master Agent is responsible.
