| DWORD GetWinFlags(void) |
The GetWinFlags function retrieves the current Windows system and memory configuration.
This function has no parameters.
The return value specifies the current system and memory configuration if the function is successful.
The configuration returned by GetWinFlags can be a combination of the following values:
| Value | Meaning |
| WF_80x87 | System contains an Intel math coprocessor. |
| WF_CPU086 | System CPU is an 8086. Windows 3.1 will not return this flag. |
| WF_CPU186 | System CPU is an 80186. Windows 3.1 will not return this flag. |
| WF_CPU286 | System CPU is an 80286. |
| WF_CPU386 | System CPU is an 80386. |
| WF_CPU486 | System CPU is an i486. |
| WF_ENHANCED | Windows is running in 386-enhanced mode. The WF_PMODE flag is always set when WF_ENHANCED is set. |
| WF_PAGING | Windows is running on a system with paged memory. |
| WF_PMODE | Windows is running in protected mode. In Windows 3.1, this flag is always set. |
| WF_STANDARD | Windows is running in standard mode. The WF_PMODE flag is always set when WF_STANDARD is set. |
| WF_WIN286 | Same as WF_STANDARD. |
| WF_WIN386 | Same as WF_ENHANCED. |
| WF_WLO | Identifies an application running Windows-emulation libraries in a non-Windows operating system. |
The following example uses the GetWinFlags function to display information about the current Windows system configuration:
int len;
char szBuf[80];
DWORD dwFlags;
dwFlags = GetWinFlags();
len = sprintf(szBuf, "system %s a coprocessor",
(dwFlags & WF_80x87) ? "contains" : "does not contain");
TextOut(hdc, 10, 15, szBuf, len);
len = sprintf(szBuf, "processor is an %s",
(dwFlags & WF_CPU286) ? "80286" :
(dwFlags & WF_CPU386) ? "80386" :
(dwFlags & WF_CPU486) ? "i486" : "unknown");
TextOut(hdc, 10, 30, szBuf, len);
len = sprintf(szBuf, "running in %s mode",
(dwFlags & WF_ENHANCED) ? "enhanced" : "standard");
TextOut(hdc, 10, 45, szBuf, len);
len = sprintf(szBuf, "%s WLO",
(dwFlags & WF_WLO) ? "using" : "not using");
TextOut(hdc, 10, 60, szBuf, len);
