reallocBuffer

Used throughout dplug:dsp to avoid reliance on GC. Important: Size 0 is special-case to free the slice. This works a bit like alignedRealloc except with slices as input. You MUST use consistent alignement thoughout the lifetime of this buffer.

(

ref T[] buffer

size_t length

int alignment = 1

)

Parameters

buffer T[]: Existing allocated buffer. Can be null. Input slice length is not considered.
length size_t: Desired slice length.
alignment int: Alignement if the slice has allocation requirements, 1 else. Must match for deallocation.

Examples

import std.stdio;

struct MyDSP
{
nothrow @nogc:

    void initialize(int maxFrames)
    {
        // mybuf points to maxFrames frames
        mybuf.reallocBuffer(maxFrames);
    }   

    ~this()
    {
        // If you don't free the buffer, it will leak.    
        mybuf.reallocBuffer(0); 
    }

private:
    float[] mybuf;
