csx_RequestSocketMask(9F)				   Kernel Functions for Drivers 				 csx_RequestSocketMask(9F)

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.
