NetWkstaGetInfo获取系统版本信息

NetWkstaGetInfo可用获取操作系统的基本信息：

#pragma comment(lib, "netapi32.lib")
#include <lm.h>
void OSInfo()
{
    DWORD dwLevel = 102;
    LPWKSTA_INFO_102 pBuf = NULL;
    NET_API_STATUS nStatus;
    LPWSTR pszServerName = NULL;

    nStatus = NetWkstaGetInfo(pszServerName,
        dwLevel,
        (LPBYTE*)&pBuf);
    //
    // If the call is successful,
    //  print the workstation data.
    //
    if (nStatus == NERR_Success)
    {
        printf("\n\tPlatform: %d\n", pBuf->wki102_platform_id);
        wprintf(L"\tName:     %s\n", pBuf->wki102_computername);
        printf("\tVersion:  %d.%d\n", pBuf->wki102_ver_major,
            pBuf->wki102_ver_minor);
        wprintf(L"\tDomain:   %s\n", pBuf->wki102_langroup);
        wprintf(L"\tLan Root: %s\n", pBuf->wki102_lanroot);
        wprintf(L"\t# Logged On Users: %d\n", pBuf->wki102_logged_on_users);
    }
    //
    // Otherwise, indicate the system error.
    //
    else
        fprintf(stderr, "A system error has occurred: %d\n", nStatus);
    //
    // Free the allocated memory.
    //
    if (pBuf != NULL)
        NetApiBufferFree(pBuf);
}
