Function Documentation

SYSINFO_API BOOL SysInfoDll_GetSystemInfo_WMI ( SYSINFO_WMI *  SysInfo  ) 

Call this function to return system information via WMI (Windows Management Information).

The call is synchronous and can take some time to return.

Note:
This will initialize the COM object library for the current thread. As such, if you have already initialized COM, this will fail. Either run in a thread, use the SysInfoDll_GetSystemInfo_WMI_async version, or close the currently open COM library.
Parameters:
[out] SysInfo Pointer to a structure to store the system information
Returns:
TRUE if successful, otherwise FALSE
SYSINFO_API BOOL SysInfoDll_GetSystemInfo_WMI_async ( SYSINFO_WMI *  SysInfo_WMI  ) 

Call this function to return system information via WMI (Windows Management Information).

The call is asynchronous as it can take some time to return.

Remarks:
After calling this function, you will need to call SysInfoDll_GetSystemInfo_WMI_async_complete to check that the system information is available. If it is complete, then the information will be returned with the call to SysInfoDll_GetSystemInfo_WMI_async_complete.
Parameters:
[out] SysInfo_WMI Pointer to a structure to store the system information
Returns:
TRUE if successful, otherwise FALSE
SYSINFO_API BOOL SysInfoDll_GetSystemInfo_WMI_async_complete ( SYSINFO_WMI *  SysInfo,
int *  iProgressPercent 
)

Call this function to check whether the system information from a previous call to SysInfoDll_GetSystemInfo_WMI_async is available.

If it is complete, then the information will be returned with this call.

Parameters:
[out] SysInfo Pointer to a structure to store the system information
[out] iProgressPercent Pointer to an integer to store the current percent progress
Returns:
TRUE if the system information is successfully retrieved, otherwise FALSE
SYSINFO_API wchar_t* SysInfoDll_GetHDDSummaryLine ( SYSINFO_WMI *  SysInfo_WMI,
wchar_t *  line,
int  iLen 
)

Call this function to retrieve a summary string for the system disks (based on exising SysInfo_WMI infomration).

Parameters:
[in] SysInfo_WMI Pointer to WMI System Information already retrieved.
[out] line Pointer to a string to store a summary system disks.
[in] iLen Size of the line string buffer.
Returns:
summary string
