MAKEDLLVERULL macro

-description

Used to pack DLL version information into a ULONGLONG value.

-parameters

-param major

The major version number.

-param minor

The minor version number.

-param build

The build number.

-param qfe

The hotfix number that identifies the service pack.

-remarks

This macro is used in conjunction with DllGetVersion to pack version information into a form that can easily be compared to the ullVersion member of a DLLVERSIONINFO2 structure. It is defined as follows.

#define MAKEDLLVERULL(major, minor, build, sp) \
        (((ULONGLONG)(major) << 48) | \
         ((ULONGLONG)(minor) << 32) | \
         ((ULONGLONG)(build) << 16) | \
         ((ULONGLONG)(   sp) <<  0))

For most purposes, you only need to assign values to the major and minor version numbers. The remaining two parameters can be set to zero. The following code fragment illustrates how to use MAKEDLLVERULL to determine whether a DLL is version 4.71 or later. The VersionInfo structure is the DLLVERSIONINFO2 structure returned by DllGetVersion.

if(VersionInfo.ullVersion >= MAKEDLLVERULL(4, 71, 0, 0))
{
    ...
}
