.SH NAME
|
|
\fBgetstr\fR, \fBwgetstr\fR, \fBmvgetstr\fR,
|
|
\fBmvwgetstr\fR,
|
|
\fBwgetnstr\fR - accept character strings from \fBncurses\fR terminal keyboard
|
|
.SH SYNOPSIS
|
|
\fB#include <ncurses.h>\fR
|
|
|
|
\fBint getstr(char *str);\fR
|
|
.br
|
|
\fBint wgetstr(WINDOW *win, char *str);\fR
|
|
.br
|
|
\fBint mvgetstr(int y, int x, char *str);\fR
|
|
.br
|
|
\fBint mvwgetstr(WINDOW *win, int y, int x, char *str);\fR
|

|
|
\fBint wgetnstr(WINDOW *win, char *str, int n);\fR

.SH DESCRIPTION
|
|
The function \fBgetstr\fR is equivalent to a series of calls to \fBgetch\fR,
|
|
until a newline or carriage return is received (the terminating character is
|
|
not included in the returned string). The resulting value is placed in the
|
|
area pointed to by the character pointer \fIstr\fR.
|
|
|
|
\fBwgetnstr\fR reads at most \fIn\fR characters, thus preventing a possible
|
|
overflow of the input buffer. Any attempt to enter more characters (other
|
|
than the terminating newline or carriage return) causes a beep.
|
|
|
|
The user's erase and kill characters are interpreted. If keypad
|
|
mode is on for the window, \fBKEY_LEFT\fR and \fBKEY_BACKSPACE\fR
|
|
are both considered equivalent to the user's kill character.
|
|
.SH RETURN VALUE
|
|
All routines return the integer \fBERR\fR upon failure and an integer value
|
|
other than \fBERR\fR upon successful completion.
|
|
.SH BUGS
|
|
When the window is in keypad mode and the user types any special key
|
|
other than those named above, the `character' value appended to the
|
|
string by the ncurses implementation is predictable but not useful
|
|
(being, in fact, the low-order eight bits of the key's KEY_ value).
|
|
|
|
The SVr4.0 documentation claims that "special keys (such as function
|
|
keys, "home" key, "clear" key, \fIetc\fR.) are interpreted" without
|
|
giving details. It lies. The actual behavior is like that of ncurses.
|
|
.SH NOTES
|
|
Note that \fBgetstr\fR, \fBmvgetstr\fR, and \fBmvwgetstr\fR may be macros.
