SYSINFO_API int SysInfoDll_Smart_Init	(	bool	debug,
		wchar_t *	iDebugFile = `NULL`,
		bool	iRecordTEC = `true`
	)

Call this function to initialize usage of the SMART set of APIs.

This function should only be called once. The call enumerates through all detected drives, initializes the proper structures and retrieves SMART values. If SysInfoDll_Smart_Init is not called first, subsequent SysInfo SMART API calls will fail.

Note:: SysInfoDll_Smart_Cleanup must be called afterwards to de-allocate memory.

Parameters:

`[in]`	debug	A flag specifying if debug messages should be logged
`[in]`	iDebugFile	The name of the debug file to write to. If NULL, "SmartDiskDebug.log" will be used.
`[in]`	iRecordTEC	A flag specifying if we want to record and write all SMART attributes to a binary file for the purpose of TEC prediction. This value defaults to true.

Returns:: SMART_STATUS_SUCCESS (0) if no error or negative error code

SYSINFO_API void SysInfoDll_Smart_Cleanup ( void )

Remarks:: It de-allocates all memory that was allocated by SysInfoDll_Smart_Init.

Note:: SysInfoDll_Smart_Cleanup should be called after SysInfoDll_Smart_Init.

SYSINFO_API int SysInfoDll_Smart_Refresh ( bool iRecordTEC = false )

Call this function to refresh (and re-probe) all SMART devices. If iRecordTEC is true, it records S.M.A.R.T. values for all the available S.M.A.R.T. devices discovered.
