clan_symbol_p clan_symbol_add	(	clan_symbol_p *	table,
		char *	identifier,
		int	type
	)

clan_symbol_add function: This function adds a new clan_symbol_t in the symbol table whose address is provided as a parameter. If the symbol table is empty (NULL), the new node will become its first element. A new node is added only if an existing node with the same identifier does not already exist. It returns the pointer to the symbol table node corresponding to the identifier.

Parameters:

[in,out]	table	The address of the symbol table.
[in]	identifier	The identifier of the symbol we want to add.
[in]	type	The new symbol type.

clan_symbol_array_to_strings function: this functions builds (and returns a pointer to) an osl_strings_t structure containing the symbol strings contained in an array of symbols of length nb. The symbol string order is the same as the one in the symbol array.

Parameters:

[in]	sarray	The symbol array.
[in]	size	The size of the symbol array.

clan_symbol_get_type function: This function returns the type of the symbol with identifier "identifier" in the symbol table whose first element is "symbol". If the symbol with the specified identifier is not found, it returns -1.

Parameters:

[in]	symbol	The first node of the list of symbols.
[in]	identifier	The identifier we want to know the type.

Returns:: The type of the symbol corresponding to the identifier.

clan_symbol_p clan_symbol_lookup	(	clan_symbol_p	symbol,
		char *	identifier
	)

clan_symbol_lookup function: This function searches the symbol table for a symbol with the identifier provided as parameter. It returns the pointer to the symbol if it already exists inside the table, NULL otherwise.

Parameters:

[in]	symbol	The first node of the list of symbols.
[in]	identifier	The identifier we are looking for.

Returns:: The symbol corresponding to identifier, NULL if it doesn't exist.

clan_symbol_p clan_symbol_lookup_by_key	(	clan_symbol_p	symbol,
		int	key
	)

clan_symbol_lookup_by_key function: This function searches the symbol table for a symbol with the key provided as parameter. It returns the pointer to the symbol if it already exists inside the table, NULL otherwise.

Parameters:

[in]	symbol	The first node of the list of symbols.
[in]	key	The key of the searched symbol.

Returns:: The symbol corresponding to the key, or NULL if it doesn't exist.

clan_symbol_p clan_symbol_malloc ( )

clan_symbol_malloc function: This function allocates the memory space for a clan_symbol_t structure and sets its fields with default values. Then it returns a pointer to the allocated space.

Returns:: A newly allocated symbol set with default values.

int clan_symbol_nb_of_type	(	clan_symbol_p	symbol,
		int	type
	)

clan_symbol_nb_of_type function: this function returns the number of symbols of a given type in the symbol table.

Parameters:

[in]	symbol	The top of the symbol table.
[in]	type	The type of the elements.

Returns:: The number of symbols of the provoded type in the symbol table.

int clan_symbol_new_iterator	(	clan_symbol_p *	table,
		clan_symbol_p *	array,
		char *	id,
		int	depth
	)

clan_symbol_new_iterator function: this function return 1 if it succeeds to register (or to update) an iterator in the symbol table and to add it to the iterator array. It returns 0 otherwise. The reason for failure can be that the symbol is already in use for something else than an iterator.

Parameters:

[in,out]	table	The symbol table.
[in,out]	array	The iterator array.
[in]	id	The textual name of the iterator.
[in]	depth	The current loop depth.

Returns:: 1 on success, 0 on failure.

void clan_symbol_print	(	FILE *	file,
		clan_symbol_p	symbol
	)

clan_symbol_print function: This function prints the content of a clan_symbol_t structure (*symbol) into a file (file, possibly stdout).

Parameters:

[in]	file	File where informations are printed.
[in]	symbol	The symbol whose information have to be printed.

void clan_symbol_print_structure	(	FILE *	file,
		clan_symbol_p	symbol,
		int	level
	)

clan_symbol_print_structure function: Displays a clan_symbol_t structure (*symbol) into a file (file, possibly stdout) in a way that trends to be understandable without falling in a deep depression or, for the lucky ones, getting a headache... It includes an indentation level (level) in order to work with others print_structure functions.

Parameters:

[in]	file	File where informations are printed.
[in]	symbol	The symbol whose information have to be printed.
[in]	level	Number of spaces before printing, for each line.

struct osl_generic* clan_symbol_to_arrays ( clan_symbol_p symbol ) [read]

clan_symbol_to_arrays function: this function generates an arrays extension from the symbol table passed as an argument. It embeds it in an osl_generic_t structure before returning it.

Parameters:

[in] symbol The symbol table.

Returns:: An arrays structure with all the arrays of the symbol table.

struct osl_generic* clan_symbol_to_strings	(	clan_symbol_p	symbol,
		int	type
	)		`[read]`

clan_symbol_to_strings function: this function builds (and returns a pointer to) an osl_generic_t structure containing the symbol strings of a given type in the symbol table. The osl_generic_t is a shell for an osl_strings_t which actually stores the symbol strings. The symbol strings are sorted in the same order as they appear in the symbol table. If there is no corresponding symbol in the table, it returns NULL.

Parameters:

[in]	symbol	The top of the symbol table.
[in]	type	The type of the elements.

Returns:: An osl_generic_t with the symbol strings of the given type.
