NAME

initscr, newterm − screen initialization functions

SYNOPSIS

#include <curses.h>

WINDOW ∗initscr(void);

SCREEN ∗newterm(char ∗type, FILE ∗outfp, FILE ∗infp);

ARGUMENTS

typeIs a string defining the terminal type to be used in place of TERM. 

outfpIs a pointer to a file to be used for output to the terminal. 

infpIs the pointer to a file to be used for input to the terminal. 

DESCRIPTION

The initscr() function initializes X/Open Curses data structures, determines the terminal type, and ensures the first call to refresh(3XC) clears the screen. 

The newterm() function opens a new terminal with each call.  It should be used instead of initscr() when the program interacts with more than one terminal.  It returns a variable of type SCREEN, which should be used for later reference to that terminal.  Before program termination, endwin() should be called for each terminal. 

The only functions that you can call before calling initscr() or newterm() are filter(3XC), ripoffline(3XC), slk_init(3XC), and use_env(3XC). 

RETURN VALUES

On success, the initscr() function returns a pointer to stdscr; otherwise, initscr() does not return. 

On success, the newterm() function returns a pointer to the specified terminal; otherwise, a null pointer is returned. 

ERRORS

None.
