## Function Documentation

## pw_core_add_listener()

SPA_EXPORT void pw_core_add_listener | ( | struct pw_core * | core,
|  | struct spa_hook * | listener,
|  | const struct pw_core_events * | events,
|  | void * | data
| ) |  |

Add a new event listener to a core.

## pw_core_find_global()

SPA_EXPORT struct pw_global* pw_core_find_global | ( | struct pw_core * | core,
|  | uint32_t | id
| ) |  |

Find a core global by id.

Parameters

  core | the core
  id | the global id

References pw_global_get_permissions(), and PW_PERM_IS_R.

## pw_core_for_each_global()

SPA_EXPORT int pw_core_for_each_global | ( | struct pw_core * | core,
|  | int(*)(void *data, struct pw_global *global) | callback,
|  | void * | data
| ) |  |

Iterate the globals of the core.

The callback should return 0 to fetch the next item, any other value stops the iteration and returns the value. When all callbacks return 0, this function returns 0 when all globals are iterated.

Parameters

  core | the core

References pw_global_get_permissions(), and PW_PERM_IS_R.

## pw_core_get_global()

SPA_EXPORT struct pw_global* pw_core_get_global | ( | struct pw_core * | core | ) |

Get the core global object.

## pw_core_get_info()

SPA_EXPORT const struct pw_core_info* pw_core_get_info | ( | struct pw_core * | core | ) |

Get the core info object.

## pw_core_get_main_loop()

SPA_EXPORT struct pw_loop* pw_core_get_main_loop | ( | struct pw_core * | core | ) |

get the core main loop

## pw_core_get_properties()

SPA_EXPORT const struct pw_properties* pw_core_get_properties | ( | struct pw_core * | core | ) |

Get the core properties.

## pw_core_get_support()

SPA_EXPORT const struct spa_support* pw_core_get_support | ( | struct pw_core * | core,
|  | uint32_t * | n_support
| ) |  |

Get the core support objects.

## pw_core_get_type()

SPA_EXPORT struct pw_type* pw_core_get_type | ( | struct pw_core * | core | ) |

Get the type object of a core.
