## Function Documentation

## ◆ gp_abilities_list_append()

int gp_abilities_list_append | ( | CameraAbilitiesList * | list,
|  | CameraAbilities | abilities
| ) |  |

Append the abilities to the list.

Parameters

  list | CameraAbilitiesList
  abilities | CameraAbilities

Returns
  a gphoto2 error code

This function is called by a camera library on camera_abilities() in order to inform libgphoto2 about a supported camera model.

Referenced by camera_abilities().

## ◆ gp_abilities_list_count()

int gp_abilities_list_count | ( | CameraAbilitiesList * | list | ) |

Count the entries in the supplied list.

Parameters

  list | a CameraAbilitiesList

Returns
  The number of entries or a gphoto2 error code

## ◆ gp_abilities_list_detect()

int gp_abilities_list_detect | ( | CameraAbilitiesList * | list,
|  | GPPortInfoList * | info_list,
|  | CameraList * | l,
|  | GPContext * | context
| ) |  |

Parameters

  list | a CameraAbilitiesList
  info_list | the GPPortInfoList of ports to use for detection
  l | a CameraList that contains the autodetected cameras after the call
  context | a GPContext

Tries to detect any camera connected to the computer using the supplied list of supported cameras and the supplied info_list of ports.

Returns
  a gphoto2 error code

## ◆ gp_abilities_list_free()

int gp_abilities_list_free | ( | CameraAbilitiesList * | list | ) |

Free the given CameraAbilitiesList object.

Parameters

  list | a CameraAbilitiesList

Returns
  a gphoto2 error code

## ◆ gp_abilities_list_get_abilities()

int gp_abilities_list_get_abilities | ( | CameraAbilitiesList * | list,
|  | int | index,
|  | CameraAbilities * | abilities
| ) |  |

Retrieve the camera abilities of entry with supplied index number.

Parameters

  list | a CameraAbilitiesList
  index | index
  abilities | pointer to CameraAbilities for returned data.

Returns
  a gphoto2 error code

## ◆ gp_abilities_list_load()

int gp_abilities_list_load | ( | CameraAbilitiesList * | list,
|  | GPContext * | context
| ) |  |
