NAME
       tickit_pen_has_attr - test if a pen has a given attribute


SYNOPSIS
       #include <tickit.h>

       bool tickit_pen_has_attr(TickitPen *pen, TickitPenAttr attr);
       bool tickit_pen_nondefault_attr(TickitPen *pen, TickitPenAttr attr);

       Link with -ltickit.


DESCRIPTION
       tickit_pen_has_attr()  tests  whether a pen instance has a given attribute defined on it. It returns true
       if the corresponding tickit_pen_set_*_attr() function has been called since  construction,  or  the  last
       time it was cleared. This is true even if the attribute has been set to its default value.

       tickit_pen_nondefault_attr()  tests  whether  a  pen  instance  has a given attribute defined with a non-
       default value. It returns true if the attribute is set to a value that is not the default,  or  false  if
       the attribute is absent, or set to the default value for that attribute type.


RETURN VALUE
       tickit_pen_has_attr() and tickit_pen_nondefault_attr() return a boolean.
