Library Initialization

enum WpInitFlags

Flags for wp_init()

Values:

enumerator WP_INIT_PIPEWIRE = (1 << 0)

Initialize PipeWire by calling pw_init()

enumerator WP_INIT_SPA_TYPES = (1 << 1)

Initialize support for dynamic spa types. See wp_spa_dynamic_type_init()

enumerator WP_INIT_SET_PW_LOG = (1 << 2)

Override PipeWire’s logging system with WirePlumber’s one

enumerator WP_INIT_SET_GLIB_LOG = (1 << 3)

Set wp_log_writer_default() as GLib’s default log writer function

enumerator WP_INIT_ALL = 0xf

Initialize all of the above

enum WpLookupDirs

Flags to specify lookup directories.

Values:

enumerator WP_LOOKUP_DIR_ENV_DATA = (1 << 1)

$WIREPLUMBER_DATA_DIR

enumerator WP_LOOKUP_DIR_ENV_TEST_SRCDIR = (1 << 2)

$G_TEST_SRCDIR

enumerator WP_LOOKUP_DIR_XDG_CONFIG_HOME = (1 << 10)

void wp_init(WpInitFlags flags)

Initializes WirePlumber and PipeWire underneath.

flags can modify which parts are initialized, in cases where you want to handle part of this initialization externally.

Parameters:

• flags – initialization flags

const char *wp_get_library_version(void)

Gets the WirePlumber library version.

Since

0.4.12

Returns:

WirePlumber library version

const char *wp_get_library_api_version(void)

Gets the WirePlumber library API version.

Since

0.4.12

Returns:

WirePlumber library API version

const gchar *wp_get_module_dir(void)

Gets the WirePlumber module directory.

Returns:

WirePlumber’s module directory

gchar *wp_find_file(WpLookupDirs dirs, const gchar *filename, const char *subdir)

Returns the full path of filename as found in the hierarchy of configuration and data directories.

Since

0.4.2

Parameters:

• dirs – the directories to look into

• filename – the name of the file to search for

• subdir – (nullable): the name of the subdirectory to search in, inside the configuration directories

Returns:

(transfer full): An allocated string with the configuration file path or NULL if the file was not found.

WpIterator *wp_new_files_iterator(WpLookupDirs dirs, const gchar *subdir, const gchar *suffix)

Creates an iterator to iterate over configuration files in the subdir of the configuration directories.

Files are sorted across the hierarchy of configuration and data directories with files in higher-priority directories shadowing files in lower-priority directories. Files are only checked for existence, a caller must be able to handle read errors.

Since

0.4.2

Note

the iterator may contain directories too; it is the responsibility of the caller to ignore or recurse into those.

Parameters:

• dirs – the directories to look into

• subdir – (nullable): the name of the subdirectory to search in, inside the configuration directories

• suffix – (nullable): The filename suffix, NULL matches all entries

Returns:

(transfer full): a new iterator iterating over strings which are absolute paths to the configuration files found
