_get_winmajor 

Visual Studio 2005

Gets the current value of the _winmajor global variable. This function is obsolete; consider using GetVersionEx which provides more precise and correct information.


errno_t _get_winmajor( 
   int * pValue 
);

Parameters

[out] pValue

A pointer to an integer to be filled with the current major version number of the Windows operating system.

Returns zero if successful; an error code on failure. If pValue is NULL, the invalid parameter handler is invoked as described in Parameter Validation. If execution is allowed to continue, this function sets errno to EINVAL and returns EINVAL.

The _winmajor global variable contains the major version of the Windows operating system.
