Gathering information about a workstation

Some times you need information about a workstation, for example if you want to know if a workstation is not running WindowsNT and you try some NT-specific job without any chance. I think this pseudo-routine can be helpful.

#include <what_you_need.h>
/*Usually:
#include <lmcons.h>
#include <lmwksta.h>
#include <lmserver.h>
#include <lmerr.h>*/

//	Network API job - obtain network info about selected machine.
BOOL
_GetWkstaInformation100()
{
	LPBYTE lpBuf;
	LPCSTR lpcstrWkstaName = (LPCSTR)m_strWkstaName;

	int iwLength = 2 * (MAX_COMPUTERNAME_LENGTH + 1);
	WCHAR lpwWkstaName[2 * (MAX_COMPUTERNAME_LENGTH + 1)];

	lpwWkstaName[0] = '\0';
	MultiByteToWideChar(CP_ACP, 0, lpcstrWkstaName, -1, lpwWkstaName, iwLength);

	typedef NET_API_STATUS (NET_API_FUNCTION *NETWKPROC)(LPWSTR, DWORD, LPBYTE *);

	NETWKPROC _procNetWkstaGetInfo = (NETWKPROC)
		(GetProcAddress(theApp.m_hNetDLL, _T("NetWkstaGetInfo")));

	if(_procNetWkstaGetInfo)
	{
		NET_API_STATUS nasRetVal = (*_procNetWkstaGetInfo)(lpwWkstaName, 100, (LPBYTE*)&lpBuf);

		if(nasRetVal == NERR_Success)
		{
			WKSTA_INFO_100 *pWkstaInfo = (WKSTA_INFO_100 *)lpBuf;
			DWORD dwPlatformId = pWkstaInfo->wki100_platform_id;

			if(dwPlatformId != PLATFORM_ID_NT)
			{
				//[ERROR]Not a Windows NT Workstation - if useful.
				return FALSE;
			}
			else
			  return TRUE;
		}
		else
		{
			//[ERROR] System error. Call GetLastError, FormatMessage, etc.
			return FALSE;
		}
	}
	else
	{
		//[ERROR]Unable to find procedure NetWkstaGetInfo in netapi32.dll.
		return FALSE;
	}
}
