 ## API
 ```C
-	int hl_init(void);
-	int hl_deinit(void);
+int hl_init(void);

 ```
 These functions are responsible for the library's "life time".
 `hl_init()` must be called before any other library function.
 `hl_deinit()` will ensure all occupied memory is freed.
 
 ```C
-	void render_string(const char * const string, const char * const mode);
+void render_string(const char * const string, const char * const mode);
 ```
 This function matches _string_ against all known highlighting rules and dispatches the appropriate callback depending on _mode_.

 The universal way to add a new pattern to be recognized is with:

 However the regex engine can be overridden:
