csx_ReleaseConfiguration(Kernel Functions for Drivcsx_ReleaseConfiguration(9F)NAMEcsx_ReleaseConfiguration - release PC Card and socket configuration
SYNOPSIS
#include <sys/pccard.h>
int32_t csx_ReleaseConfiguration(client_handle_t ch, release_config_t
*rc);
INTERFACE LEVEL
Solaris DDI Specific (Solaris DDI)
PARAMETERS
ch Client handle returned from csx_RegisterClient(9F).
rc Pointer to a release_config_t structure.
DESCRIPTION
This function returns a PC Card and socket to a simple memory only
interface and sets the card to configuration zero by writing a 0 to the
PC card's COR (Configuration Option Register).
Card Services may remove power from the socket if no clients have indi‐
cated their usage of the socket by an active csx_RequestConfigura‐
tion(9F) or csx_RequestWindow(9F).
Card Services is prohibited from resetting the PC Card and is not
required to cycle power through zero (0) volts.
After calling csx_ReleaseConfiguration() any resources requested via
the request functions csx_RequestIO(9F), csx_RequestIRQ(9F), or
csx_RequestWindow(9F) that are no longer needed should be returned to
Card Services via the corresponding csx_ReleaseIO(9F), csx_Relea‐
seIRQ(9F), or csx_ReleaseWindow(9F) functions. csx_ReleaseConfigura‐
tion() must be called to release the current card and socket configura‐
tion before releasing any resources requested by the driver via the
request functions named above.
STRUCTURE MEMBERS
The structure members of release_config_t are:
uint32_t Socket; /* socket number */
The Socket field is not used in Solaris, but for portability with other
Card Services implementations, it should be set to the logical socket
number.
RETURN VALUES
CS_SUCCESS
Successful operation.
CS_BAD_HANDLE
Client handle is invalid or csx_RequestConfiguration(9F) not done.
CS_BAD_SOCKET
Error getting or setting socket hardware parameters.
CS_NO_CARD
No PC card in socket.
CS_UNSUPPORTED_FUNCTION
No PCMCIA hardware installed.
CONTEXT
This function may be called from user or kernel context.
