PA_UPDATE_SET	Replace the entire property list with the new one. Don't keep any of the old data around
PA_UPDATE_MERGE	Merge new property list into the existing one, not replacing any old entries if they share a common key with the new property list.
PA_UPDATE_REPLACE	Merge new property list into the existing one, replacing all old entries that share a common key with the new property list.

Function Documentation

void pa_proplist_clear ( pa_proplist * p )

Remove all entries from the property list object.

Since:: 0.9.11

int pa_proplist_contains	(	pa_proplist *	p,
		const char *	key
	)

Returns 1 if an entry for the specified key is existant in the property list.

Since:: 0.9.11

pa_proplist* pa_proplist_copy ( pa_proplist * t )

Allocate a new property list and copy over every single entry from the specific list.

Since:: 0.9.11

void pa_proplist_free ( pa_proplist * p )

Free the property list.

Since:: 0.9.11

pa_proplist* pa_proplist_from_string ( const char * str )

Allocate a new property list and assign key/value from a human readable string.

Since:: 0.9.15

int pa_proplist_get	(	pa_proplist *	p,
		const char *	key,
		const void **	data,
		size_t *	nbytes
	)

Return the the value for the specified key.

Will return a NUL-terminated string for string entries. The pointer returned will point to an internally allocated buffer. The caller should make a copy of the data before the property list is accessed again.

Since:: 0.9.11

const char* pa_proplist_gets	(	pa_proplist *	p,
		const char *	key
	)

Return a string entry for the specified key.

Will return NULL if the data is not valid UTF-8. Will return a NUL-terminated string in an internally allocated buffer. The caller should make a copy of the data before accessing the property list again.

Since:: 0.9.11

int pa_proplist_isempty ( pa_proplist * t )

Returns 0 when the proplist is empty, positive otherwise.

Since:: 0.9.15

const char* pa_proplist_iterate	(	pa_proplist *	p,
		void **	state
	)

Iterate through the property list.

The user should allocate a state variable of type void* and initialize it with NULL. A pointer to this variable should then be passed to pa_proplist_iterate() which should be called in a loop until it returns NULL which signifies EOL. The property list should not be modified during iteration through the list -- except for deleting the current looked at entry. On each invication this function will return the key string for the next entry. The keys in the property list do not have any particular order.

Since:: 0.9.11

pa_proplist* pa_proplist_new ( void )

Allocate a property list.

Since:: 0.9.11

int int pa_proplist_set	(	pa_proplist *	p,
		const char *	key,

int pa_proplist_setf	(	pa_proplist *	p,
		const char *	key,
		const char *	format,
			...
	)

Append a new string entry to the property list, possibly overwriting an already existing entry with the same key.

Return the number of entries on the property list.

Since:: 0.9.15

char* pa_proplist_to_string ( pa_proplist * p )

Format the property list nicely as a human readable string.

This works very much like pa_proplist_to_string_sep() and uses a newline as seperator and appends one final one. Call pa_xfree() on the result.

Since:: 0.9.11

char* pa_proplist_to_string_sep	(	pa_proplist *	p,
		const char *	sep
	)

Format the property list nicely as a human readable string and choose the seperator.

Call pa_xfree() on the result.

Since:: 0.9.15

Examples:: pacat.c.

int pa_proplist_unset	(	pa_proplist *	p,
		const char *	key
	)

Removes a single entry from the property list, identified be the specified key name.

Since:: 0.9.11

int pa_proplist_unset_many	(	pa_proplist *	p,
		const char *const	keys[]
	)

Similar to pa_proplist_remove() but takes an array of keys to remove.

The array should be terminated by a NULL pointer. Return -1 on failure, otherwise the number of entries actually removed (which might even be 0, if there where no matching entries to remove).

Since:: 0.9.11

void pa_proplist_update	(	pa_proplist *	p,
		pa_update_mode_t	mode,
		pa_proplist *	other
	)

Merge property list "other" into "p", adhering the merge mode as specified in "mode".
