Device API

Collaboration diagram for Device API:

Detailed Description

The device object provides a common interface to the functionality that is shared by all device proxies (in OOP parlance, it is a base class).

In general, this object should not be instantiated or accessed directly: use the device proxies instead.


struct  _playerc_device_t
 Common device info. More...


typedef _playerc_device_t playerc_device_t
 Common device info.


void playerc_device_init (playerc_device_t *device, playerc_client_t *client, int code, int index, playerc_putmsg_fn_t putmsg)
 Initialise the device.
void playerc_device_term (playerc_device_t *device)
 Finalize the device.
int playerc_device_subscribe (playerc_device_t *device, int access)
 Subscribe the device.
int playerc_device_unsubscribe (playerc_device_t *device)
 Unsubscribe the device.
int playerc_device_hascapability (playerc_device_t *device, uint32_t type, uint32_t subtype)
 Request capabilities of device.
int playerc_device_get_intprop (playerc_device_t *device, char *property, int32_t *value)
 Request an integer property.
int playerc_device_set_intprop (playerc_device_t *device, char *property, int32_t value)
 Set an integer property.
int playerc_device_get_dblprop (playerc_device_t *device, char *property, double *value)
 Request a double property.
int playerc_device_set_dblprop (playerc_device_t *device, char *property, double value)
 Set a double property.
int playerc_device_get_strprop (playerc_device_t *device, char *property, char **value)
 Request a string property.
int playerc_device_set_strprop (playerc_device_t *device, char *property, char *value)
 Set a string property.
