The pValueBuf is a * pointer to an array of ulong_t. The size of array must be large enough to * accomodate the getproc, nextproc, testproc, setproc and undoproc requests for  * retrieving all objects from a tabular row in multiple varbinds.. Envoy snmp will * serialize all the transactions, subsequent getproc, nextproc, testproc, setproc  * and/or undoproc will not be called until the current one is completed. Therefore,  * the pValueBuf pointer can be reused each time a new getproc, nextproc, testproc, * setproc and/or undoproc is started. The pOctetBuf is a pointer to buffer allocated * specifically for octet string. For getproc and nextproc, the memory pointed to by the * pOctetBuf must be either statically or dynamically allocated and the <dynamic> boolean * flag must be set to TRUE if memory is dynamically allocated. If dynamic memory  * allocation is used, Envoy snmp requires that the memory is allocated using  * SNMP_memory_alloc() and must be marked as dynamic when the getproc_got_string() is  * called so that Envoy SNMP will free the memory using SNMP_memory_free() when the  * packet gets encoded. For that reason, the pOctetBuf pointer can be reused for the next  * transaction after the getproc_got_string() is called. For testproc, setproc and/or  * undoproc, there is no restriction to how the memory must be allocated. However, the * <dynamic> boolean flag must still be set accordingly. If SNMP_memory_alloc() is used * to allocated the memory, application must free the memory using SNMP_memory_free()  * when the testproc, setproc and/or undoproc is completed (envoy snmp will not free the  * memory in this case).  */typedef struct envoyRequest {    SEM_ID        envoyBSem;       /* binary semaphore for synchronization into Envoy */     ulong_t       *pValueBuf;      /* pointer to array of ulong_t */    ushort_t      numValueBuf;     /* number of valueBuf allocated */    ushort_t      bufUsedCnt;      /* number of valueBuf used */    char          *pOctetBuf;      /* pointer to buffer for octet string */    ulong_t       octetBufLen;     /* sizeof data pointed to by pOctetBuf */    BOOL          dynamic;         /* is pOctetBuf dynamically allocated? */    mApiObject_t  *pObjectList;    /* pointer to array of MIB API objec info */    ulong_t       *pObjCookie;     /* pointer to array of ulong_t for object cookie */} envoyRequest_t;/* misc covertion routines */IMPORT void copy_oids( OIDC_T *best_inst, OIDC_T *tlist, int tcount );IMPORT ushort_t mApi2EnvoyErrorGet( ushort_t mApiError );/* prototype for adding/removing subtree to SNMP agent MIB tree */STATUS  ospf_envoy_snmpdTreeAdd( char *pTreeOidStr, MIBNODE_T *pTreeAddr,                                  SEM_ID ospf_envoyBSem );void ospf_envoy_snmpdTreeRemove( char *pTreeOidStr, SEM_ID ospf_envoyBSem ); /* prototype for routine to build MIB API TEST/SET/UNDO request message */ IMPORT int ospf_envoy_buildSetReq( int tcount, OIDC_T *tlist, SNMP_PKT_T *pktp, VB_T *vbp,                                   envoyRequest_t *pEnvoyReq, mApiRequest_t *pRequest,                                   mApiReqType_t reqType, int mApiOidOffset );/* prototype for routine to mark a varbind (used by testproc, setproc and undoproc) */IMPORT void ospf_envoy_markVarbind( VB_T *vbp, SNMP_PKT_T *pktp, mApiRequest_t *pRequest,                                    mApiReqType_t reqType );/* prototype for routine to build MIB API GET/GET NEXT request message */IMPORT STATUS ospf_envoy_buildGetReq( int tcount, OIDC_T *tlist, VB_T *vbp,                                      envoyRequest_t *pEnvoyReq,                                       mApiRequest_t *pRequest, int mApiOidOffset );/* prototype for routine to process MIB API GET/GET NEXT response */IMPORT void ospf_envoy_processGetResp( VB_T *vbp, SNMP_PKT_T *pktp,                                        envoyRequest_t *pEnvoyReq,                                        mApiRequest_t *pRequest, mApiReqType_t reqType,                                       int mApiOidOffset );/* prototype for routine to process MIB API GET/GET NEXT response for scalar objects */IMPORT void ospf_envoy_processScalarGetResp( VB_T *vbp, SNMP_PKT_T *pktp,                                             envoyRequest_t *pEnvoyReq,                                              mApiRequest_t *pRequest,                                              mApiReqType_t reqType, int mApiOidOffset );/* prototype for misc method routines related to this Envoy Management Facility */IMPORT void ospfEnvoy_undo( OIDC_T lastmatch, int tcount, OIDC_T *tlist,                            SNMP_PKT_T *pktp, VB_T *vbp );IMPORT void ospf_envoy_clearBuffer( envoyRequest_t *pEnvoyReq );IMPORT void ospf_envoy_mApiDestroy( envoyRequest_t *pEnvoyReq );IMPORT envoyRequest_t *ospf_envoy_mApiInit( int numBuf );/* porototypes for setting snmp errors */IMPORT void ospf_envoy_setGenError( SNMP_PKT_T *pktp, VB_T *vbp, mApiReqType_t reqType );IMPORT void ospf_envoy_setNoSuchNameError( SNMP_PKT_T *pktp, VB_T *vbp,                                            mApiReqType_t reqType );IMPORT void ospf_envoy_processGetRespError( SNMP_PKT_T *pktp, VB_T *vbp,                                             mApiReqType_t reqType, int mApiErr );#ifdef __cplusplus}#endif /* __cplusplus */#endif /* __INCospf_mib_envoy_apih */
