/**
* Tests whether every element of a reinterpreted complex number ndarray is truthy.
*
* @private
* @param {Object} x - object containing ndarray meta data
* @param {string} x.dtype - data type
* @param {Collection} x.data - data buffer
* @param {NonNegativeIntegerArray} x.shape - dimensions
* @param {IntegerArray} x.strides - stride lengths
* @param {NonNegativeInteger} x.offset - index offset
* @param {string} x.order - specifies whether `x` is row-major (C-style) or column-major (Fortran-style)
* @returns {boolean} result
*
* @example
* var Float64Array = require( '@stdlib/array/float64' );
*
* // Create a data buffer:
* var xbuf = new Float64Array( [ 1.0, 2.0 ] );
*
* // Define the shape of the input array:
* var shape = [];
*
* // Define the array strides:
* var sx = [ 0 ];
*
* // Define the index offset:
* var ox = 0;
*
* // Create the input ndarray-like object:
* var x = {
*     'dtype': 'complex128',
*     'data': xbuf,
*     'shape': shape,
*     'strides': sx,
*     'offset': ox,
*     'order': 'row-major'

* // Test elements:
* var out = every0d( x );
