Solaris DDI Specific (Solaris DDI)

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.

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.

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.

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.

These functions may be called from user or kernel context.
