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);
context
: ContextszDir
: Data storage patheventMask
: event maskeventId
: Log record ID, retireves from the first record if it is 0amount
: Maximum log amount, retrieves all after eventID if it is 0logsObj
: Pointer of storing the log record addressnumLog
: 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.
If successfully done, BS_SDK_SUCCESS
will be returned.
If there is an error, the corresponding error code will be returned.
