Chapter 3 – System Functions
3.1.36 ApiReadRecData
Prototype:
AiInt16 ApiReadRecData ( AiUInt32 ul_ModuleHandle, AiUInt8 biu,
TY_API_BM_REC *api_rec_stat, void *lpBuf,
AiUInt32 *lBytesRead );
Driver Command:
none
Purpose:
This function copies the 1553 MILBus data recorded by the Bus Monitor while in
