#include <sys/pccard.h> int32_t csx_ReleaseConfiguration(client_handle_t ch, release_config_t *rc);
Client handle returned from csx_RegisterClient(9F).
Pointer to a release_config_t structure.
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 configuration before releasing any resources requested by the driver via the request functions named above.
uint32_t Socket; /* socket number */
The Socket field is not used in illumos, but for portability with other Card Services implementations, it should be set to the logical socket number.
Successful operation.
Client handle is invalid or csx_RequestConfiguration(9F) not done.
Error getting or setting socket hardware parameters.
No PC card in socket.
No PCMCIA hardware installed.
