NAME

csx_RequestSocketMask, csx_ReleaseSocketMask - set or clear the client's client event mask  

SYNOPSIS

#include <sys/pccard.h>

int32_t csx_RequestSocketMask(client_handle_t ch, request_socket_mask_t *sm);

int32_t csx_ReleaseSocketMask(client_handle_t ch, release_socket_mask_t *rm);  

INTERFACE LEVEL

Solaris DDI Specific (Solaris DDI)  

PARAMETERS

ch Client handle returned from csx_RegisterClient(9F).

sm Pointer to a request_socket_mask_t structure.

rm Pointer to a release_socket_mask_t structure.

 

DESCRIPTION

The function csx_RequestSocketMask() sets the client's client event mask and enables the client to start receiving events at its event callback handler. Once this function returns successfully, the client can start receiving events at its event callback handler. Any pending events generated from the call to csx_RegisterClient(9F) will be delivered to the client after this call as well. This allows the client to set up the event handler mutexes before the event handler gets called.

csx_RequestSocketMask() must be used before calling csx_GetEventMask(9F) or csx_SetEventMask(9F) for the client event mask for this socket.

The function csx_ReleaseSocketMask() clears the client's client event mask.  

STRUCTURE MEMBERS

The structure members of request_socket_mask_t are:

  uint32_t    Socket;       /* socket number */
  uint32_t    EventMask;    /* event mask to set or return */

The structure members of release_socket_mask_t are:

  uint32_t    Socket;       /* socket number */

The fields are defined as follows:

Socket Not used in Solaris, but for portability with other Card Services implementations, it should be set to the logical socket number.

EventMask This field is bit-mapped. Card Services performs event notification based on this field. See csx_event_handler(9E) for valid event definitions and for additional information about handling events.

 

RETURN VALUES

CS_SUCCESS Successful operation.

CS_BAD_HANDLE Client handle is invalid.

CS_IN_USE csx_ReleaseSocketMask() has not been done.

CS_BAD_SOCKET csx_RequestSocketMask() has not been done.

CS_UNSUPPORTED_FUNCTION No PCMCIA hardware installed.

 

CONTEXT

These functions may be called from user or kernel context.
