USB Exported Control API > BS2_GetLogSmallBlobFromDir

[+ 2.6.4] Gets certain amount of logs based on the event mask from USB exported data in an efficient way.
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.


#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);


  • [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

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.
