Function Documentation

const char* get_id_str

(

ident *

id

)

Returns a string represented by an ident.

Returns the string represented by id. This string is NULL terminated. The string may not be changed.

Parameters

id

the ident

Returns

cp a string

size_t get_id_strlen

(

ident *

id

)

Returns the length of the string represented by an ident.

Parameters

id

the ident

Returns

len the length of the string

int id_contains_char	(	ident *	id,
		char	c
	)

Test if identifier contains a given character.

Parameters

id	the ident
c	the character

Returns

1 if character is contained, 0 otherwise

int id_is_prefix	(	ident *	prefix,
		ident *	id
	)

Test if prefix is a prefix of ident id.

Parameters

prefix	the prefix
id	the ident

Returns

1 if prefix is prefix of id, 0 otherwise

int id_is_suffix	(	ident *	suffix,
		ident *	id
	)

Test if suffix is a suffix of ident id.

Parameters

suffix	the suffix
id	the ident

Returns

1 if suffix is suffix of id, 0 otherwise

ident* id_mangle	(	ident *	first,
		ident *	scnd
	)

mangle: Returns a new ident that represents firstscnd.

ident* id_mangle3	(	const char *	prefix,
		ident *	middle,
		const char *	suffix
	)

Returns a new ident that represents 'prefixscndsuffix'.

ident* id_mangle_dot	(	ident *	first,
		ident *	scnd
	)

mangle dot: Returns a new ident that represents first.scnd.

ident* id_mangle_u	(	ident *	first,
		ident *	scnd
	)

mangle underscore: Returns a new ident that represents first_scnd.

ident* id_unique

(

const char *

tag

)

helper function for creating unique idents.

It contains an internal counter and replaces a "%u" inside the tag with the counter.

ident* new_id_from_chars	(	const char *	str,
		size_t	len
	)

Store a string and create an ident.

Stores a string in the ident module and returns a handle for the string. Copies the string. This version takes non-zero-terminated strings.

Parameters

str	the string (or whatever) which shall be stored
len	the length of the data in bytes

Returns

id a handle for the generated ident

ident* new_id_from_str

(

const char *

str

)

Store a string and create an ident.

Stores a string in the ident module and returns a handle for the string.

Copies the string. str must be zero terminated

Parameters

str	the string which shall be stored

Returns

id a handle for the generated ident
