Caution
Call 'AllocateBuffer(int, int, out AudioQueueBuffer*)' instead.
Allocates an audio queue object for variable-bit-rate buffers.
public AudioToolbox.AudioQueueStatus AllocateBufferWithPacketDescriptors(int bufferSize, int nPackets, out IntPtr audioQueueBuffer);[System.Obsolete("Call 'AllocateBuffer(int, int, out AudioQueueBuffer*)' instead.")]
public AudioToolbox.AudioQueueStatus AllocateBufferWithPacketDescriptors(int bufferSize, int nPackets, out IntPtr audioQueueBuffer);member this.AllocateBufferWithPacketDescriptors : int * int * nativeint -> AudioToolbox.AudioQueueStatus[<System.Obsolete("Call 'AllocateBuffer(int, int, out AudioQueueBuffer*)' instead.")>]
member this.AllocateBufferWithPacketDescriptors : int * int * nativeint -> AudioToolbox.AudioQueueStatusParameters
- bufferSize
- Int32
Size of the audio data in the allocated buffer, in bytes.
- nPackets
- Int32
The number of elements in the packet descriptions array in the returned buffer.
- audioQueueBuffer
-
IntPtr
nativeint
The allocated buffer on return. Cast this to a pointer to a AudioQueueBuffer to use it.
Returns
Ok on success and the audioQueueBuffer pointing to the buffer, otherwise the error code.

Remarks
Use the AllocateBuffer(Int32, AudioQueueBuffer*) to allocate buffers that will be used with fixed bit rate encodings.
Use FreeBuffer(IntPtr) to free the buffer (if not it will be freed when this audio queue is disposed).
