Function Documentation

void _sem_add_label	(	SemTable *	sem,
		SemanticID	s,
		Symbol	label_type,
		char *	label
	)

add a name to a definition

Parameters

[in]	sem	is the semantic table where symbols and structures are defined
[in]	s	the semantic id of the definition to add a label to
[in]	label_type	is a symbol of the label type to add
[in]	label	text of the label

Examples (from test suite):

    SemanticID s;

    spec_is_true(__sem_get_by_label(G_sem,"DEFINITIONS",&s,SYS_CONTEXT));
    spec_is_sem_equal(s,DEFINITIONS);
    spec_is_false(__sem_get_by_label(G_sem,"DEFINITIONS",&s,INTERNET_CONTEXT));

    spec_is_true(_sem_get_by_label(G_sem,"OCTET_STREAM",&s));
    spec_is_sem_equal(s,OCTET_STREAM);
    spec_is_true(semeq(s,OCTET_STREAM));

    spec_is_false(_sem_get_by_label(G_sem,"non existent symbol",&s));

T* _sem_get_label	(	SemTable *	sem,
		SemanticID	s,
		Symbol	label_type
	)

get one of a symbol's labels

Parameters

[in]	sem	is the semantic table where symbols and structures are define
[in]	s	the Symbol to return the label of
[in]	s	the Symbol to return the label of

Returns

label or NULL if the definition couldn't be found

Note

the label returned is a pointer to the actual label in the definition. it must not be changed or modified! Clone it if you need to.

Examples (from test suite):

    spec_is_str_equal(t2s(_sem_get_label(G_sem,CONTENT_TYPE,HTTP_HEADER_LABEL)),"(HTTP_HEADER_LABEL:Content-Type)");
    spec_is_str_equal(t2s(_sem_get_label(G_sem,CONTENT_TYPE,TEST_SYMBOL_SYMBOL)),"(ENGLISH_LABEL:CONTENT_TYPE)");

char* _sem_get_name	(	SemTable *	sem,
		SemanticID	s
	)

get symbol's name

Parameters

[in]	sem	is the semantic table where symbols and structures are define
[in]	s	the Symbol to return the label of

Returns

cstring surface of the first label in the definition

Examples (from test suite):

    spec_is_str_equal(_sem_get_name(G_sem,TEST_INT_SYMBOL),"TEST_INT_SYMBOL");
    spec_is_str_equal(_sem_get_name(G_sem,NULL_SYMBOL),"NULL_SYMBOL");
    spec_is_str_equal(_sem_get_name(G_sem,NULL_STRUCTURE),"NULL_STRUCTURE");
    spec_is_str_equal(_sem_get_name(G_sem,NULL_PROCESS),"NULL_PROCESS");
    spec_is_str_equal(_sem_get_name(G_sem,DEFINITIONS),"DEFINITIONS");
    spec_is_str_equal(_sem_get_name(G_sem,INTEGER),"INTEGER");
    spec_is_str_equal(_sem_get_name(G_sem,IF),"IF");
