- These functions are described in the XSI Curses standard, Issue 4,
- which adds <EM>const</EM> qualifiers to the arguments.
+ X/Open Curses, Issue 4 describes these functions. It specifies no
+ error conditions for them.
- The Single Unix Specification, Version 2 states that <STRONG>insnstr</STRONG> and
- <STRONG>winsnstr</STRONG> perform wrapping. This is probably an error, since it makes
- this group of functions inconsistent. Also, no implementation of
- curses documents this inconsistency.
+ Issue 4 distinguished <STRONG>insnstr</STRONG> and <STRONG>winsnstr</STRONG> by stating they "do not
+ perform wrapping". This was probably an error, since it makes this
+ group of functions inconsistent. No implementation of <EM>curses</EM> documents
+ this inconsistency, and Issue 7 removed it.
- X/Open states that the entire string is inserted if <EM>n</EM> is less than 1.
- This is probably an error, because it is inconsistent with other
- functions, and differs from the SVr4 and X/Open implementations on
- Solaris.
+ Issue 4 states that the entire string is inserted if <EM>n</EM> is less than 1.
+ This is probably an error, because it is inconsistent with other
+ functions, and differs from the SVr4 <EM>curses</EM> and Solaris <EM>xcurses</EM>
+ implementations. Nevertheless, Issue 7 retains it.
