67 These routines return a string of characters in <EM>str</EM>, extracted starting
68 at the current cursor position in the named window. Attributes are
69 stripped from the characters. The four functions with <EM>n</EM> as the last
70 argument return a leading substring at most <EM>n</EM> characters long (exclu-
71 sive of the trailing NUL).

75 All of the functions return <STRONG>ERR</STRONG> upon failure, or the number of charac-
76 ters actually read into the string.
78 X/Open Curses defines no error conditions. In this implementation:
80 <STRONG>o</STRONG> If the <EM>win</EM> parameter is null, an error is returned,
82 <STRONG>o</STRONG> If the <EM>chstr</EM> parameter is null, an error is returned,
84 Functions with a "mv" prefix first perform a cursor movement using
85 <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
86 the window pointer is null.
