USB Exported Control API > BS2_GetLogSmallBlobFromDir —- ===== BS2_GetLogSmallBlobFromDir===== [+ 2.6.4] Retrieves logs filtered by EventMask from the USB exported data. The difference from BS2_GetLogBlobFromDir which is using BS2EventBlob is that the parameter imageObj in BS2EventSmallBlob is changed to pointer for memory efficiency. Except this, everything is the same. ==== Declaration ==== <code cpp> #include “BS_API.h” int BS2_GetLogSmallBlobFromDir(void* context, const char* szDir, uint16_t eventMask, BS2_EVENT_ID eventId, uint32_t amount, BS2EventSmallBlob logsObj, uint32_t* numLog); </code> BS2EventSmallBlob구조체 보기 ==== Parameter ==== * [In] context : Context * [In] szDir : Data storage path * [In] eventMask : event mask * [In] eventId : Log record ID, retireves from the first record if it is 0 * [In] amount : Maximum log amount, retrieves all after eventID if it is 0 * [Out] logsObj : Pointer of storing the log record address * [Out] numLog : The number of log records NOTE The logsObj variable needs to return the memory to the system by the BS2_ReleaseObject function after being used. ==== Return Value ==== If successfully done, BS_SDK_SUCCESS will be returned. If there is an error, the corresponding error code will be returned. ==== See Also ==== BS2_AllocateUsbContext BS2_ReleaseUsbContext BS2_GetUserDatabaseInfoFromDir BS2_GetUserListFromDir BS2_GetUserInfosFromDir BS2_GetUserDatasFromDir BS2_GetUserInfosExFromDir BS2_GetUserDatasExFromDir BS2_GetLogFromDir BS2_GetFilteredLogFromDir BS2_GetLogBlobFromDir
