ENCODERPROC Delegate

public delegate int ENCODERPROC(
	int handle,
	int channel,
	IntPtr buffer,
	int length,
	int maxout,
	IntPtr user
)

Public Delegate Function ENCODERPROC ( 
	handle As Integer,
	channel As Integer,
	buffer As IntPtr,
	length As Integer,
	maxout As Integer,
	user As IntPtr
) As Integer

Parameters

handle

Type: SystemInt32
The encoder handle.

channel

Type: SystemInt32
The channel that the encoder is set on.

buffer

Type: SystemIntPtr
Buffer containing the sample data on input, and containing the encoded data on output.

length

Type: SystemInt32
The number of bytes in the buffer... -1 = the encoder is being freed (no data in the buffer).

maxout

Type: SystemInt32
The maximum amount of encoded data that can be placed in the buffer.

user

Type: SystemIntPtr
The user instance data given when BASS_Encode_StartUser(Int32, String, BASSEncode, ENCODERPROC, IntPtr) was called.

Return Value

If the encoder output exceeds the outmax value, then only the first outmax bytes should be delivered and the remainder retained. The function will be called again immediately to get the remainder.

Instead of returning the data in buffer, it is also possible to provide the encoded data via BASS_Encode_UserOutput(Int32, Int64, IntPtr, Int32), which also adds the ability to update previous data (eg. headers).
