Typedef Documentation

uat_copy_cb_t

typedef void *(* uat_copy_cb_t) (void *dest, const void *source, size_t len)

Copy CB copy(dest, source, len)

Used to duplicate the contents of one record to another. Optional, memcpy will be used if not given.

uat_free_cb_t

typedef void(* uat_free_cb_t) (void *record)

Free CB free(record)

Destroy the contents of a record, possibly freeing some fields. Do not free the container itself, this memory is owned by the UAT core. Optional if the record contains no pointers that need to be freed.

uat_reset_cb_t

typedef void(* uat_reset_cb_t) (void)

Reset DB

Used to free resources associated with a UAT loaded from file (e.g. post_update_cb) Optional.

uat_update_cb_t

typedef bool(* uat_update_cb_t) (void *record, char **error)

Update CB update(record,&error)

Validates the contents of the record contents, to be called after any record fields had been updated (either from file or after modifications in the GUI).

Optional, the record will be considered valid if the callback is omitted. It must return true if the contents are considered valid and false otherwise in which case the failure reason is set in 'error'. The error string will be freed by g_free.

XXX: This should only validate the record. Any changes to the record made here will not be persistent if the UAT is saved again, unless the same changes are also done to a new record created by the copy cb, e.g. by having the the copy callback call this. It should probably be made into a const void* to make that clear.

Function Documentation

uat_cleanup()

void uat_cleanup

(

void

)

Cleanup all UATs.

uat_destroy()

WS_DLL_PUBLIC void uat_destroy

(

uat_t *

uat

)

Free and deregister a single UAT.

uat_find()

uat_t * uat_find

(

char *

name

)

Given a UAT name or filename, find its pointer.

Parameters

name	The name or filename of the uat

Returns

A pointer to the uat on success, NULL on failure.

uat_load()

WS_DLL_PUBLIC bool uat_load	(	uat_t *	uat_in,
		const char *	filename,
		char **	err
	)

Populate a UAT using its file.

Parameters

uat_in	Pointer to a uat. Must not be NULL.
filename	Filename to load, NULL to fetch from current profile.
err	Upon failure, points to an error string.

Returns

true on success, false on failure.

uat_load_str()

bool uat_load_str	(	uat_t *	uat_in,
		const char *	entry,
		char **	err
	)

Create or update a single UAT entry using a string.

Parameters

uat_in	Pointer to a uat. Must not be NULL.
entry	The string representation of the entry. Format must match what's written to the uat's output file.
err	Upon failure, points to an error string.

Returns

true on success, false on failure.

uat_new()

WS_DLL_PUBLIC uat_t * uat_new	(	const char *	name,
		size_t	size,
		const char *	filename,
		bool	from_profile,
		void *	data_ptr,
		unsigned *	num_items_ptr,
		unsigned	flags,
		const char *	help,
		uat_copy_cb_t	copy_cb,
		uat_update_cb_t	update_cb,
		uat_free_cb_t	free_cb,
		uat_post_update_cb_t	post_update_cb,
		uat_reset_cb_t	reset_cb,
		uat_field_t *	flds_array
	)

Create a new UAT.

Parameters

name	The name of the table
size	The size of the structure
filename	The filename to be used (either in userdir or datadir)
from_profile	true if profile directory to be used
data_ptr	Although a void*, this is really a pointer to a null terminated array of pointers to the data
num_items_ptr	A pointer with number of items
flags	flags indicating what this UAT affects
help	A pointer to help text
copy_cb	A function that copies the data in the struct
update_cb	Will be called when a record is updated
free_cb	Will be called to destroy a struct in the dataset
post_update_cb	Will be called once the user clicks the Apply or OK button
reset_cb	Will be called to destroy internal data
flds_array	A pointer to an array of uat_field_t structs

Returns

A freshly-allocated and populated uat_t struct.

uat_set_default_values()

WS_DLL_PUBLIC void uat_set_default_values	(	uat_t *	uat_in,
		const char *	default_values[]
	)

Provide default field values for a UAT.

This can be used to provide forward compatibility when fields are added to a UAT.

Parameters

uat_in	Pointer to a uat. Must not be NULL.
default_values	An array of strings with default values. Must be the same length as flds_array. Individual elements can be NULL, and can be used to distinguish between mandatory and optional fields, e.g. { NULL, NULL, NULL, "default value (optional)" }

Todo:

Use this to provide default values for empty tables.
