(6) (parallelism TS v2)

Constructs a new const_where_expression or where_expression.

1-6) constructs a where_expression from given mask and value parameters.

Contents

[edit] Parameters

1-4)
mask - the simd_mask object
value - reference to the object that mask applies on
5-6)
mask - the mask of type bool
value - reference to the scalar that mask applies on

[edit] Return value

The constructed const_where_expression or where_expression.

[edit] Notes

5-6) uses implementation defined type of mask, so that implicit conversions from other types to bool is disabled.
