Kernel Functions for Drivers         csx_ReleaseConfiguration(9F)



NAME
     csx_ReleaseConfiguration - release PC Card and socket confi-
     guration

SYNOPSIS
     #include 



     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  indicated  their  usage  of  the  socket  by an active
     csx_RequestConfiguration(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_ReleaseIRQ(9F),   or
     csx_ReleaseWindow(9F)  functions. csx_ReleaseConfiguration()
     must be called to release the current card and socket confi-
     guration  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 */

Kernel Functions for Drivers         csx_ReleaseConfiguration(9F)



     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.
