"""
The smartcard.scard module is a simple wrapper on top of the C language
PCSC SCardXXX API.

The smartcard.scard module is the lower layer of the pyscard
framework that provides a higher level interface.

You should avoid using the smartcard.scard package directly, and use the
pyscard directly because:

 - smartcard.scard being a C wrapper, the code tends to look like C code
   written in python syntax

 - the smartcard package provides higher level abstractions (e.g.
   CardType, CardConnection), and makes programming easier since it is
   totally written in Python

You can still use the smartcard.scard package if you want to write your
own framework, or if you want to perform quick-and-dirty port of C
language programs using SCardXXX calls, or if there are features of
SCardXXX API that you want to use and that are not available in the
pyscard library.

Introduction

The smartcard.scard module is a Python wrapper around PCSC smart card base
services.  On Windows, the wrapper is performed around the smart card base
components winscard library.  On linux and OS X, the wrapper is performed
around the PCSC-lite library.


The smartcard.scard module provides mapping for the following API functions,
depending on the Operating System:

    Value of state              Meaning
    SCARD_STATE_UNAWARE         The application is unaware of the current state, and would like to know. The use of this value results in an immediate return from state transition monitoring services. This is represented by all bits set to zero

    SCARD_STATE_CHANGED         There is a difference between the state believed by the application, and the state known by the resource manager. When this bit is set, the application may assume a significant state change has occurred on this reader
    SCARD_STATE_UNKNOWN         The given reader name is not recognized by the resource manager. If this bit is set, then SCARD_STATE_CHANGED and SCARD_STATE_IGNORE will also be set
    SCARD_STATE_UNAVAILABLE     The actual state of this reader is not available. If this bit is set, then all the following bits are clear
    SCARD_STATE_EMPTY           There is no card in the reader. If this bit is set, all the following bits will be clear
    SCARD_STATE_PRESENT         There is a card in the reader
    SCARD_STATE_ATRMATCH        There is a card in the reader with an ATR matching one of the target cards. If this bit is set, SCARD_STATE_PRESENT will also be set. This bit is only returned on the SCardLocateCards function
    SCARD_STATE_EXCLUSIVE       The card in the reader is allocated for exclusive use by another application. If this bit is set, SCARD_STATE_PRESENT will also be set
    SCARD_STATE_INUSE           The card in the reader is in use by one or more other applications, but may be connected to in shared mode. If this bit is set, SCARD_STATE_PRESENT will also be set
    SCARD_STATE_MUTE            There is an unresponsive card in the reader
