Prototype:
AiReturn FdxFwIrig2StructIrig ( const TY_FDX_FW_IRIG_TIME *px_FwIrigTime,
TY_FDX_IRIG_TIME *px_IrigTime )
Driver Command:
none
Purpose:
This function can be used to convert an IRIG time in the format used by the Firmware to a
structured format. This function is helpful since the format of the IRIG time used by the
firmware is different to the format often used in the Application Library.
Input:
TY_FDX_FW_IRIG_TIME *px_FwIrigTime
typedef struct {
AiUInt32
ul_TtHigh;
AiUInt32
ul_TtLow;
} TY_FDX_FW_IRIG_TIME;
