NAME

       gii_cmd_event,  gii_cmd_nodata_event  - LibGII commands and information
       events

SYNOPSIS

       #include <ggi/events.h>

       typedef struct {

           COMMON_DATA;

           uint32_t  code;

       } gii_cmd_nodata_event;

       #define GII_CMD_DATA_MAX  (248-sizeof(gii_cmd_nodata_event))

       typedef struct gii_cmd_event {

           COMMON_DATA;

           uint32_t  code;
           uint8_t   data[GII_CMD_DATA_MAX];

       } gii_cmd_event;

DESCRIPTION

       These are used internally either to the application or the kernel.  The
       same event is used for both Command and Information events.

GENERATED EVENTS

       gii_cmd_event  is  the  basic structure for evCommand and evInformation
       events.  It may need to be casted to some other structure (depending on
       code) to access the data.

STRUCTURE MEMBERS

       code   The command or request code.

       data   Provides  raw access to the device and/or command specific data.
              The recipient must not store references to the data. If the data
              information is needed afterwards, copy it!

DEVICE INFORMATION

       One  use  of  evCommand is to convey some capabilities of a GII device,
       via the GII_CMDCODE_GETDEVINFO command code.
