- The XSI Curses standard, Issue 4, describes these func-
- tions. It changes the argument type of the attribute-ma-
- nipulation functions <STRONG>slk_attron</STRONG>, <STRONG>slk_attroff</STRONG>, <STRONG>slk_attrset</STRONG>
- to be <STRONG>attr_t</STRONG>, and adds <STRONG>const</STRONG> qualifiers. The format codes
- <STRONG>2</STRONG> and <STRONG>3</STRONG> for <STRONG>slk_init</STRONG> and the function <STRONG>slk_attr</STRONG> are specif-
- ic to ncurses.
+ The XSI Curses standard, Issue 4, described the soft-key
+ functions, with some differences from SVr4 curses:
+
+ <STRONG>o</STRONG> It added functions like the SVr4 the attribute-manipu-
+ lation functions <STRONG>slk_attron</STRONG>, <STRONG>slk_attroff</STRONG>, <STRONG>slk_attrset</STRONG>
+ which use <STRONG>attr_t</STRONG> parameters, along with a reserved
+ <EM>opts</EM> parameter.
+
+ One of these new functions (<STRONG>slk_attr_set</STRONG>) also has a
+ color-pair parameter.
+
+ <STRONG>o</STRONG> It added <STRONG>const</STRONG> qualifiers to parameters (unnecessari-
+ ly), and
+
+ <STRONG>o</STRONG> It added <STRONG>slk_color</STRONG>.
+
+ The format codes <STRONG>2</STRONG> and <STRONG>3</STRONG> for <STRONG>slk_init</STRONG> and the function
+ <STRONG>slk_attr</STRONG> are specific to ncurses.
