Sensoray 826 - Manual (Page 12)

Return Values
The return value is always zero.
Remarks
This function should be called when a process (e.g., an application program) has finished interacting with the board's
I/O interfaces, to free system resources that are no longer needed. Any API functions that are blocking will return
immediately, with return value S826_ERR_SYSCLOSED. The board's circuitry is not reset by this function; all
registers and I/O states are preserved.
3.5 Status Functions
3.5.1 S826_VersionRead
The S826_VersionRead function returns API, driver, and board version information.
int S826_VersionRead(
uint board, // board identifier
uint *api, // API version
uint *driver, // driver version
uint *bdrev, // circuit board version
uint *fpgarev // FPGA version
);
Parameters
board
826 board number. This must match the settings of the board's dip switches as described in section 2.2.
api
Pointer to a buffer that will receive the API version info. The hexadecimal value is formatted as 0xXXYYZZZZ,
where XX = major version, YY = minor version, and ZZZZ = build.
driver
Pointer to a buffer that will receive the driver version info. The hexadecimal info is formatted as 0xXXYYZZZZ,
where XX = major version, YY = minor version, and ZZZZ = build.
boardrev
Pointer to a buffer that will receive the version number of the 826's circuit board.
fpgarev
Pointer to a buffer that will receive the board's FPGA version info. The hexadecimal info is formatted as
0xXXYYZZZZ, where XX = major version, YY = minor version, and ZZZZ = build.
Return Values
If the function succeeds, the return value is zero.
If the function fails, the return value is an error code.
3.5.2 S826_TimestampRead
The S826_TimestampRead function returns the current value of the timestamp generator.
int S826_TimestampRead(
uint board, // board identifier
uint *timestamp // current timestamp
);
