Function `rt.lifetime._d_arraycatnTX`

Concatenate multiple arrays at once


						
				extern(C) void[] _d_arraycatnTX
				(
				

				  const(TypeInfo) ti,
				

				  scope byte[][] arrs
				

				);

This is more efficient than repeatedly concatenating pairs of arrays because the total size is known in advance.

` void main() { int[] a, b, c; int[] res = a ~ b ~ c; // d_arraycatnTX(typeid(int[]), // [(cast(byte*)a.ptr)[0..a.length], (cast(byte*)b.ptr)[0..b.length], (cast(byte*)c.ptr)[0..c.length]]); } `

Parameters

Name	Description
ti	type of arrays to concatenate and resulting array
arrs	array of arrays to concatenate, cast to `byte[]` while keeping `.length` the same

Returns

newly created concatenated array, .length equal to the total element length despite void type
