The initscr routine is used to initialize single terminal environment.
Syntax |
 |
#include <curses.h>
WINDOW *initscr();
|
Return Values |
|
On success, a pointer to stdscr is returned; otherwise, a null pointer is returned (for example, if the console could not be opened for write; the terminal could not be initialized; or memory could not be
allocated for stdscr).
Description |
|
The initscr() routine initializes CURSES data structures, determines the terminal type, and makes sure that the first call to refresh() clears the screen. If the program interacts with only one terminal, this should be the first routine called.
If the program interacts with more than one terminal, newterm() should be called for each terminal instead of a single call to initscr().
Implementation Considerations |

Identical to XPG/3
