Chapter 3 – System Functions
3.1.37 ApiWriteRepData
Prototype:
AiInt16 ApiWriteRepData ( AiUInt32 ul_ModuleHandle, AiUInt8 biu,
TY_API_REP_STATUS *api_rep_stat, void *lpBuf,
AiUInt32 *lBytesWritten );
Driver Command:
none
Purpose:
This function copies Bus Monitored recorded entries (previously copied to an
application buffer (see System function ApiReadRecData)) from an application buffer
into the Replay Buffer Global RAM area. The replay of this data can then be started
using the ApiCmdReplayStart function.

Actual value of the Half Buffer Transmitted Interrupt counter (incremented each time a High
Speed Half Buffer Transmitted Interrupt occurs).
When the rpi_cnt value is incremented new Replay data given in parameter 'lpBuf' has been
reloaded to the Global RAM of the AIM board area.
