QUEUE_FOREACH	(	w	,

	)

bool tv_callback_equal	(	const Callback *	cb1,
		const Callback *	cb2
	)

Check whether two callbacks are equal

Parameters

[in]	cb1	First callback to check.
[in]	cb2	Second callback to check.

Returns: True if they are equal, false otherwise.

bool tv_check_lock	(	const VarLockStatus	lock,
		const char *	name,
		size_t	name_len
	)

Return true if typval is locked

Also gives an error message when typval is locked.

Parameters

[in]	lock	Lock status.
[in]	name	Variable name, used in the error message.
[in]	name_len	Variable name length. Use TV_TRANSLATE to translate variable name and compute the length. Use TV_CSTRING to compute the length with strlen() without translating.

Both #TV_… values are used for optimization purposes: variable name with its length is needed only in case of error, when no error occurs computing them is a waste of CPU resources. This especially applies to gettext.

Returns: true if variable is locked, false otherwise.

bool tv_check_num ( const typval_T *const tv )

Check that given value is a number or can be converted to it

Error messages are compatible with tv_get_number_chk() previously used for the same purpose.

Parameters

[in] tv Value to check.

Returns: true if everything is OK, false otherwise.

bool tv_check_str ( const typval_T *const tv )

Check that given value is a VimL String or can be "cast" to it.

Error messages are compatible with tv_get_string_chk() previously used for the same purpose.

Parameters

[in] tv Value to check.

Returns: true if everything is OK, false otherwise.

bool tv_check_str_or_nr ( const typval_T *const tv )

Check that given value is a number or string

Error messages are compatible with tv_get_number() previously used for the same purpose in buf*() functions. Special values are not accepted (previous behaviour: silently fail to find buffer).

Parameters

[in] tv Value to check.

Returns: true if everything is OK, false otherwise.

void tv_clear ( typval_T *const tv )

Free memory for a variable value and set the value to NULL or 0

Parameters

[in,out] tv Value to free.

void tv_copy	(	const typval_T *const	from,
		typval_T *const	to
	)

Copy typval from one location to another

When needed allocates string or increases reference count. Does not make a copy of a container, but copies its reference!

It is OK for from and to to point to the same location; this is used to make a copy later.

Parameters

[in]	from	Location to copy from.
[out]	to	Location to copy to.

int tv_dict_add	(	dict_T *const	d,
		dictitem_T *const	item
	)

Add item to dictionary

Parameters

[out]	d	Dictionary to add to.
[in]	item	Item to add.

Returns: FAIL if key already exists.

return tv_dict_add_allocated_str	(	d	,
		key	,
		key_len	,
		s
	)

int tv_dict_add_allocated_str	(	dict_T *const	d,
		const char *const	key,
		const size_t	key_len,
		char *const	val
	)

Add a string entry to dictionary

Unlike tv_dict_add_str() saves val to the new dictionary item in place of creating a new copy.

Warning: String will be freed even in case addition fails.

Parameters

[out]	d	Dictionary to add entry to.
[in]	key	Key to add.
[in]	key_len	Key length.
[in]	val	String to add.

Returns: OK in case of success, FAIL when key already exists.

int tv_dict_add_dict	(	dict_T *const	d,
		const char *const	key,
		const size_t	key_len,
		dict_T *const	dict
	)

Add a dictionary entry to dictionary

Parameters

[out]	d	Dictionary to add entry to.
[in]	key	Key to add.
[in]	key_len	Key length.
	dict	Dictionary to add. Will have reference count incremented.

Returns: OK in case of success, FAIL when key already exists.

int tv_dict_add_list	(	dict_T *const	d,
		const char *const	key,
		const size_t	key_len,
		list_T *const	list
	)

Add a list entry to dictionary

Parameters

[out]	d	Dictionary to add entry to.
[in]	key	Key to add.
[in]	key_len	Key length.
	list	List to add. Will have reference count incremented.

Returns: OK in case of success, FAIL when key already exists.

int tv_dict_add_nr	(	dict_T *const	d,
		const char *const	key,
		const size_t	key_len,
		const varnumber_T	nr
	)

Add a number entry to dictionary

Parameters

[out]	d	Dictionary to add entry to.
[in]	key	Key to add.
[in]	key_len	Key length.
[in]	nr	Number to add.

Returns: OK in case of success, FAIL when key already exists.

int tv_dict_add_special	(	dict_T *const	d,
		const char *const	key,
		const size_t	key_len,
		SpecialVarValue	val
	)

Add a special entry to dictionary

Parameters

[out]	d	Dictionary to add entry to.
[in]	key	Key to add.
[in]	key_len	Key length.
[in]	val	SpecialVarValue to add.

Returns: OK in case of success, FAIL when key already exists.
