Function Documentation

void cci_close ( cci_t cci )

Close connection to a chip card device.

Parameters:

cci

The cci_t to close. Closes connection to physical defice and frees the cci_t. Note that any transaction buffers will have to be destroyed seperately. All references to slots will become invalid.

chipcard_t cci_get_slot	(	cci_t	cci,
		unsigned int	num
	)

Retrieve a handle to a CCID slot.

Parameters:

	cci	The cci_t containing the required slot.
	num	The slot number to retrieve (zero-based).

Returns:: chipcard_t rerpesenting the required slot.

	)

Print a message in the trace log.

Parameters:

	cci	The cci_t to which the log message is pertinent.
	fmt	Format string as per printf().

Prints a message in the trace log of the specified CCI device. Does nothing if NULL was passed as tracefile paramater of cci_open.

Here is the caller graph for this function:

cci_t cci_probe	(	ccidev_t	dev,
		const char *	tracefile
	)

Connect to a physical chipcard device.

Parameters:

	dev	ccidev_t representing a physical device.
	tracefile	filename to open for trace logging (or NULL).

This function: #- Probes the USB device searching for a valid CCID interface. #- Optionally opens a file for trace logging. #- Perform any device specific initialisation.
