* See LICENSE.md for licensing information.

* Based on libusb <http://libusb.info/>:

package org.usb4java;

/**

* Structure representing a libusb session. The concept of individual libusb

* sessions allows for your program to use two libraries (or dynamically load

* two modules) which both independently use libusb. This will prevent

* interference between the individual libusb users - for example

* {@link LibUsb#setDebug(Context, int)} will not affect the other user of the

* library, and {@link LibUsb#exit(Context)} will not destroy resources that the

* other user is still using.

* Sessions are created by {@link LibUsb#init(Context)} and destroyed through

* {@link LibUsb#exit(Context)}. If your application is guaranteed to only ever

* include a single libusb user (i.e. you), you do not have to worry about

* contexts: pass NULL in every function call where a context is required. The

* default context will be used.
