Description

The inchstr() and winchstr() functions retrieve the character string (with rendition) starting at the current cursor position of the stdscr window and window win, respectively, and ending at the right margin. The mvinchstr() and mvwinchstr() functions retrieve the 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 inchnstr(), winchnstr(), mvinchnstr(), and mvwinchnstr() 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 retrieve the string, starting at the position specified by the x and y parameters.

All these functions store the retrieved character string in the object pointed to by chstr.

The complete character/attribute pair is retrieved. The character or attributes can be extracted by performing a bitwise AND on the retrieved value, using the constants A_CHARTEXT, A_ATTRIBUTES, and A_COLOR. The character string can also be retrieved without attributes by using instr(3XCURSES) set of functions.

Parameters

chstr

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

n

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

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.

Return Values

On success, these functions return OK. Otherwise, they return ERR.

Errors

None.
