__median() [1/2]

template<typename _Tp>

const _Tp & __gnu_cxx::__median	(	const _Tp &	__a,
		const _Tp &	__b,
		const _Tp &	__c )

Find the median of three values.

Parameters

__a	A value.
__b	A value.
__c	A value.

Returns

One of a, b or c.

If {l,m,n} is some convolution of {a,b,c} such that l<=m<=n then the value returned will be m. This is an SGI extension.
