NAME

instr,
innstr,
winstr,
winnstr,
mvinstr,
mvinnstr,
mvwinstr,
mvwinnstr - get a string of characters from a curses window

SYNOPSIS

#include <curses.h>

int instr(char *str);
int innstr(char *str, int n);
int winstr(WINDOW *win, char *str);
int winnstr(WINDOW *win, char *str, int n);
int mvinstr(int y, int x, char *str);
int mvinnstr(int y, int x, char *str, int n);
int mvwinstr(WINDOW *win, int y, int x, char *str);
int mvwinnstr(WINDOW *win, int y, int x, char *str, int n);

DESCRIPTION

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).

RETURN VALUE

All of the functions return ERR upon failure, or the number of characters actually read into the string.

X/Open defines no error conditions. In this implementation, if the window parameter is null or the str parameter is null, a zero is returned.

NOTES

Note that all routines except winnstr may be macros.

PORTABILITY

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.
