#define _HIDDI_NFUNCS ((sizeof(hidd_funcs_t) - sizeof(_Uint32t)) / sizeof(void *))

Number of function pointers in hidd_funcs_t. Usually assigned to nentries member.

#define HIDD_VERSION    0x0100

HID server version used to determine if clients can connect to the HID server.

#define HID_VERSION    0x0100

HID DDK version. Used by client to compatibility with connection parameters, and to determine if clients can connect to the HID server.

#define HIDD_CONNECT_WAIT    60

Represents 60 seconds, which is the recommended connection wait time.

#define HIDD_CONNECT_WILDCARD    0xFFFFFFFF

Used to indicate all vendors, all products, and all versions in hidd_device_ident_t.

#define HIDD_REPORT_EXCLUSIVE    0x02

Used by hidd_report_attach() to indicate that other clients should not be able to attach these reports; other clients will receive EBUSY.

#define HIDD_REPORT_FILTER    0x01

Used by hidd_report_attach() to indicate that other client should also receive the reports.

#define HIDD_CONNECT_FLAGS_PNP_MONITOR    0x80000000

#define HIDD_CONNECT_FLAGS_SET_STACK_SIZE    0x40000000

If set, the connection stack size is set to larger of stack_size or 16.

#define HIDD_DATA_CONSTANT    0x00000001

Flag set indicates constant; report item is read-only.

Flag unset indicates data; report item defines report modifiable device data field.

#define HIDD_DATA_VARIABLE    0x00000002

Flag set indicates variable; each field contains data from a physical control.

Flag unset indicates array; array contains index in each field that corresponds to the pressed button.

#define HIDD_DATA_RELATIVE    0x00000004

Flag set indicates absolute; data is based on fixed origin (e.g., touch events).

Flag unset indicates relative; data indicates change since last report (e.g., mouse movements).

#define HIDD_DATA_WRAP    0x00000008

Flag set indicates wrap; once data value reaches the maximum value, it can roll-over to the minimum value. Similarly, once data value reaches the minimum value, it can roll-over to the maximum value (e.g., a free-spinning dial).

Flag unset indicates no wrap; data cannot roll-over upon reaching maximum or minimum values (e.g., a slider).

#define HIDD_DATA_NONLINEAR    0x00000010

Flag set indicates nonlinear; data has been pre-processed in some way and doesn't indicate actual measurement.

Flag unset indicates linear; data represents linear relationship between measurement and reported data.

#define HIDD_DATA_NO_PREFERRED_STATE    0x00000020

Flag set indicates no preferred state; control doesn't have a default state without user interaction (e.g., a toggle button).

Flag unset indicates preferred state; control has a default state without user interaction (e.g., a push button).

#define HIDD_DATA_NULL_STATE    0x00000040

Flag set indicates null state; control doesn't send meaningful data without user interaction (e.g., a hat switch).

Flag unset indicates no null state; control sends valid data regardless of user interaction (e.g., a push button).

#define HIDD_DATA_VOLITILE    0x00000080

Only valid for feature and output reports.

Flag set indicates volatile; output can change with or without host interaction.

Flag unset indicates non-volatile; output value should be changed by host.

For input reports, this field is undefined and reserved for future use.

#define HIDD_DATA_BUFFERED_BYTES    0x00000100

Flag set indicates buffered bytes; control emits a fixed-size stream of bytes, aligned on an 8-bit boundary (e.g., a bar code reader).

Flag unset indicates bit field; control emits a single numeric quantity.
