1/6/2010
The following table shows the Smart Card Services functions with a description of the purpose of each.
| Programming element | Description |
|---|---|
This function starts a transaction, waiting for the completion of all other transactions before it begins. |
|
This function terminates all outstanding actions within a specific resource manager context. |
|
This function establishes a connection, using a specific resource manager context, between the calling application and a smart card contained by a specific reader. |
|
This function gives you direct control of the reader. You can call it any time after a successful call to SCardConnect and before a successful call to SCardDisconnect. |
|
This function terminates a connection previously opened between the calling application and a smart card in the target reader. |
|
This function completes a previously declared transaction, enabling other applications to resume interactions with the card. |
|
This function establishes the resource manager context (the scope) within which database operations are performed. |
|
This function removes an introduced smart card from the smart card subsystem. |
|
This function removes a previously introduced reader from control by the smart card subsystem. |
|
This function frees memory that has been returned from the resource manager using the SCARD_AUTOALLOCATE length designator. |
|
This function gets the current reader attributes for the specified handle. |
|
This function returns the name of the dynamic link library (DLL) containing the provider for a given card name and provider type. |
|
This function returns the globally unique identifier (GUID) of the primary service provider for a specified card. |
|
This function blocks execution until the current availability of the cards in a specific set of readers changes. |
|
This function introduces a smart card to the smart card subsystem for the active user by adding it to the smart card database. |
|
This function introduces a new name for an existing smart card reader. Smart card readers are automatically introduced to the system. |
|
This function determines whether a smart card context handle is valid. |
|
This function searches the smart card database and provides a list of named cards previously introduced to the system by a user. |
|
This function provides a list of interfaces supplied by a specified card. |
|
This function provides the list of readers within a set of named reader groups, eliminating duplicates. |
|
This function searches the readers listed in the rgReaderStates parameter for a card with an Automatic Terminal Recognition (ATR) string that matches one of the card names specified in mszCards, returning immediately with the result. |
|
This function searches the readers listed in the rgReaderStates parameter for a card with an ATR string that matches one of the ATRs specified in rgAtrMasks, returning immediately with the result. |
|
This function re-establishes an existing connection between the calling application and a smart card. |
|
This function closes an established resource manager context, freeing any resources allocated under that context, including SCARDHANDLE objects and memory allocated using the SCARD_AUTOALLOCATE length designator. |
|
This function sets the specified reader attribute for the specified handle. |
|
This function specifies the name of the DLL containing the provider for a given card name and provider type. |
|
This function provides the current status of a smart card in a reader. You can call it any time after a successful call to SCardConnect and before a successful call to SCardDisconnect. |
|
This function sends a service request to the smart card and expects to receive data back from the card. |
