LibUsbDotNet 2.2.8 GetIsoPacketBuffer Method (packet)

Convenience function to locate the position of an isochronous packet within the buffer of an isochronous transfer.

Declaration Syntax

Visual Basic

Visual C++

public IntPtr GetIsoPacketBuffer(
	int packet
)

Public Function GetIsoPacketBuffer ( _
	packet As Integer _
) As IntPtr

public:
IntPtr GetIsoPacketBuffer(
	int packet
)

Parameters

packet (Int32): The packet to return the address of.

Return Value

the base address of the packet buffer inside the transfer buffer.

Remarks

This is a thorough function which loops through all preceding packets, accumulating their lengths to find the position of the specified packet. Typically you will assign equal lengths to each packet in the transfer, and hence the above method is sub-optimal. You may wish to use GetIsoPacketBufferSimple(Int32) instead.

Note:GetIsoPacketBuffer(Int32) is roughly equivalent to libusb_get_iso_packet_buffer().

Exceptions

Exception	Condition
ArgumentOutOfRangeException	This exception is thrown if the packet requested is >= NumIsoPackets.
