10.1.4 ApiCmdReplayStatus
Prototype:
AiInt16 ApiCmdReplayStatus ( AiUInt32 ul_ModuleHandle, AiUInt8 biu,
TY_API_REP_STATUS *prep );
Driver Command:
API_REP_STATUS_READ (0x45)
Purpose:
This function is used to read the Replay Status Information. The initial value of
parameter ‘rpi_cnt’ indicates the amount of Half Buffer Transmitted Interrupts required
for writing the requested Replay file size (refer to parameter ‘fsize’ of library function
ApiCmdReplayIni).

Actual value of the Half Buffer Transmitted Interrupt counter (incremented each time a Half
Buffer Transmitted Interrupt occurs)
When the rpi_cnt value is incremented new Replay datas should be reloaded to the Shared
RAM and should be copied from the Shared RAM to the Global RAM of the AIM board area
using the library function ApiWriteRepData’.
