===== BS2_GetLogSmallBlob =====
[+ 2.6.4] Gets certain amount of logs based on the event mask.  \\
The difference from [[BS2_GetLogBlob]] which is using [[Log_Management_API#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_GetLogSmallBlob(void* context, uint32_t deviceId, uint16_t eventMask, uint32_t eventId, uint32_t amount, BS2EventSmallBlob** logsObj, uint32_t* numLog);
</code>
