fp_context_new ()

FpContext *
fp_context_new (void);

Create a new FpContext.

fp_context_enumerate ()

void
fp_context_enumerate (FpContext *context);

Enumerate all devices. You should call this function exactly once at startup. Please note that it iterates the mainloop until all devices are enumerated.

fp_context_get_devices ()

GPtrArray *
fp_context_get_devices (FpContext *context);

Get all devices. fp_context_enumerate() will be called as needed.

FP_TYPE_CONTEXT

#define FP_TYPE_CONTEXT (fp_context_get_type ())

struct FpContextClass

struct FpContextClass {
  GObjectClass parent_class;

  void         (*device_added)            (FpContext *context,
                                           FpDevice  *device);
  void         (*device_removed)          (FpContext *context,
                                           FpDevice  *device);

Class structure for FpContext instances.

FpContext

typedef struct _FpContext FpContext;

The “device-added” signal

void
user_function (FpContext *context,
               FpDevice  *device,
               gpointer   user_data)

This signal is emitted when a fingerprint reader is added.

Flags: Run Last

The “device-removed” signal

void
user_function (FpContext *context,
               FpDevice  *device,
               gpointer   user_data)

This signal is emitted when a fingerprint reader is removed.

It is guaranteed that the device has been closed before this signal is emitted. See the FpDevice removed signal documentation for more information.
