VER_SET_CONDITION macro (winnt.h)

Sets the bits of a 64-bit value to indicate the comparison operator to use for a specified operating system version attribute. This macro is used to build the dwlConditionMask parameter of the VerifyVersionInfo function.

Syntax

ULONGLONG VER_SET_CONDITION(
 ULONGLONG _m_,
 DWORD _t_,
 BYTE _c_
);

Parameters

_m_

A variable to be passed as the dwlConditionMask parameter of the VerifyVersionInfo function. The macro stores the comparison information in the bits of this variable.

Before the first call to VER_SET_CONDITION, initialize this variable to zero. For subsequent calls to VER_SET_CONDITION, pass in the variable used in the previous call.

_t_

A mask that indicates the member of the OSVERSIONINFOEX structure whose comparison type is being set. This value corresponds to one of the bits specified in the dwTypeMask parameter for the VerifyVersionInfo function. This parameter can be one of the following values.

Value Meaning
VER_BUILDNUMBER
0x0000004
 dwBuildNumber
VER_MAJORVERSION
0x0000002
 dwMajorVersion
VER_MINORVERSION
0x0000001
 dwMinorVersion
VER_PLATFORMID
0x0000008
 dwPlatformId
VER_PRODUCT_TYPE
0x0000080
 wProductType
VER_SERVICEPACKMAJOR
0x0000020
 wServicePackMajor
VER_SERVICEPACKMINOR
0x0000010
 wServicePackMinor
VER_SUITENAME
0x0000040
 wSuiteMask

_c_

The operator to use for the comparison. The VerifyVersionInfo function uses this operator to compare a specified attribute value to the corresponding value for the currently running system.

For all values of dwTypeBitMask other than VER_SUITENAME, this parameter can be one of the following values.

Value Meaning
VER_EQUAL
1
 The current value must be equal to the specified value.
VER_GREATER
2
 The current value must be greater than the specified value.
VER_GREATER_EQUAL
3
 The current value must be greater than or equal to the specified value.
VER_LESS
4
 The current value must be less than the specified value.
VER_LESS_EQUAL
5
 The current value must be less than or equal to the specified value.
 

If dwTypeBitMask is VER_SUITENAME, this parameter can be one of the following values.

Value Meaning
VER_AND
6
 All product suites specified in the wSuiteMask member must be present in the current system.
VER_OR
7
 At least one of the specified product suites must be present in the current system.

Return value

Type: ULONGLONG

The macro returns the condition mask value.

Remarks

Call this macro once for each bit set in the dwTypeMask parameter of the VerifyVersionInfo function.

Examples
