These routines return a string of characters in str,
extracted starting at the current cursor position in the
named window. Attributes are stripped from the characters.
The four functions with n as the last argument
return a leading substring at most n characters long
(exclusive of the trailing NUL).
All of the functions return ERR upon failure, or the number
of characters actually read into the string.
Note that all routines except winnstr may be macros.
The XSI Curses error conditions EILSEQ and EILOVERFLOW
associated with extended-level conformance are not yet
detected (this implementation does not yet support XPG4
multi-byte characters). SVr4 does not document whether a
length limit includes or excludes the trailing NUL.
The ncurses library extends the XSI description by allowing
a negative value for n. In this case, the functions
return the string ending at the right margin.
