list_tie
Description

Constructs a tie using a list sequence.

Synopsis
template <typename T0, typename T1,... typename TN>
list<T0&, T1&,... TN&>
list_tie(T0& x0, T1& x1... TN& xN);

For C++11 compilers, the variadic function interface has no upper bound.

For C++03 compilers, the variadic function accepts 0 to FUSION_MAX_LIST_SIZE elements, where FUSION_MAX_LIST_SIZE is a user definable predefined maximum that defaults to 10. You may define the preprocessor constant FUSION_MAX_LIST_SIZE before including any Fusion header to change the default. Example:

#define FUSION_MAX_LIST_SIZE 20
Parameters

Description
