Protocol Params in JSON Format
{
"Protocol":"MQTT",
"MQTT":{
"QoS":2,
"Retain":0
}
}
Data Extend Information and SQL Structure for Handler to Manager
SQL Params structure. This stuucture is designed for Hanlder pass its log behavior.
typedef struct SQLParams
{
int nVer; // Version of SQL Param : 1
int nAction; // 0: Insert or Update, 1: Delete, 2: Query
char *pszPrimaryKey; // NULL => Auto Index
char **pszOutDataPoint; // Pass this point to save result of query
char *pszGeneralInfo; //
int *pnStatus; // status code
void *pExtend1;
void *pExtend2;
}SQL_PARAMS, SQL_Params;
Data extened Information Structure. Handler can add more information while sending data to WISE Manager.
typedef struct DataExInfo
{
int nVer; // Data Ex Info version: 1
void *pSqlParams; // address of SQL parameters structure
void *pExtend1; // Reserved
void *pExtend2; // Reserved
}DATAEX_INFO, DataEx_Info;
