Protocol Params in JSON Format

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 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 *int; // 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; // Struct version, ( 1 ) void *pSqlParams; // address of SQL parameters structure void *pExtend1; // Reserved void *pExtend2; // Reserved }DATAEX_INFO, DataEx_Info;
