NAME
csx_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 indicated 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_ReleaseConfiguration() 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.
