ncurses_start_color — Initializes color functionality

说明

ncurses_start_color ( void ) : int

Initializes color functionality in ncurses. This function must be called before any color manipulation functions are called and after ncurses_init() is called. It is good practice to call this function right after ncurses_init().

参数

此函数没有参数。

返回值

Returns 0 on success, or -1 if the color table could not be allocated or ncurses was not initialized.

范例

Example #1 Writing a string with a specified color to the screen

<?php
ncurses_init();

// If the terminal supports colors, initialize and set active color
if (ncurses_has_colors()) {
    ncurses_start_color();
    ncurses_init_pair(1, NCURSES_COLOR_YELLOW, NCURSES_COLOR_BLUE);
    ncurses_color_set(1);
}

// Write a string at specified location
ncurses_mvaddstr(10, 10, "Hello world! Yellow on blue text!");

// Flush output to screen
ncurses_refresh();

ncurses_end();
?>
