man gii_cmd_event (Fonctions bibliothèques) - gii_cmd_event, gii_cmd_nodata_event : LibGII commands and information events
NAME
gii_cmd_event, gii_cmd_nodata_event : LibGII commands and information events
SYNOPSIS
#include <ggi/events.h>
typedef struct {
COMMON_DATA;
uint32 code;
} gii_cmd_nodata_event;
#define GII_CMD_DATA_MAX (248-sizeof(gii_cmd_nodata_event))
typedef struct gii_cmd_event {
COMMON_DATA;
uint32 code; uint8 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.
