int innstr(char *str, int n);

int instr(char *str);

int mvinnstr(int y, int x, char *str, int n);

int mvinstr(int y, int x, char *str);

int mvwinnstr(WINDOW *win, int y, int x, char *str, int n);

int mvwinstr(WINDOW *win, int y, int x, char *str);

int winstr(WINDOW *win, char *str);

int winnstr(WINDOW *win, char *str, int n);

Parameters

str

Is a pointer to an object that can hold the retrieved multibyte character string.

n

Is the number of characters not to exceed when retrieving str.

y

Is the y (row) coordinate of the starting position of the string to be retrieved.

x

Is the x (column) coordinate of the starting position of the string to be retrieved.

win

Is a pointer to the window in which the string is to be retrieved.

Description

The instr() and winstr() functions retrieve a multibyte character string (without attributes) starting at the current cursor position of the stdscr window and window win, respectively, and ending at the right margin. The mvinstr() and mvwinstr() functions retrieve a multibyte character string located at the position indicated by the x (column) and y (row) parameters (the former in the stdscr window; the latter in window win).

The innstr(), winnstr(), mvinnstr(), and mvwinnstr() functions retrieve at most n characters from the window stdscr and win, respectively. The former two functions retrieve the string starting at the current cursor position; the latter two commands return the string, starting at the position specified by the x and y parameters.

All these functions store the retrieved string in the object pointed to by str. They only store complete multibyte characters. If the area pointed to by str is not large enough to hold at least one character, these functions fail.

Only the character portion of the character/rendition pair is returned. To return the complete character/rendition pair, use winchstr().

Errors

OK

Successful completion.

ERR

An error occurred.

Usage

All functions except winnstr() may be macros.
