22 These routines return a string of characters in str, extracted starting
23 at the current cursor position in the named window. Attributes are
24 stripped from the characters. The four functions with n as the last
25 argument return a leading substring at most n characters long (exclu‐
26 sive of the trailing NUL).
27
29 All of the functions return ERR upon failure, or the number of charac‐
30 ters actually read into the string.
31
32 X/Open defines no error conditions. In this implementation, if the
33 window parameter is null or the str parameter is null, a zero is
34 returned.
35
37 Note that all routines except winnstr may be macros.
38
40 SVr4 does not document whether a length limit includes or excludes the
41 trailing NUL.
42
43 The ncurses library extends the XSI description by allowing a negative
44 value for n. In this case, the functions return the string ending at
45 the right margin.
