Linux Ncurses库：判断终端是否可以显示颜色

#include<stdio.h>
#include<stdlib.h>
#include<curses.h>

#define pri(fmt, ...)     printf("["__FILE__"] <%s>_<%d> " ,__FUNCTION__,__LINE__ );\
                        printf(fmt, ##__VA_ARGS__);

int main()
{
    pri(" ok \n");
    initscr();
    cbreak();
    noecho();

    if (has_colors() == FALSE)
        {
            pri(" ok \n");
            endwin();
            pri("Your terminal does not support color\n");
            exit(1);
        }
    endwin();    
    pri("Your terminal support color !\n");
    return 0;
}

运行后显示

[zlll@zlll-pc ballgame]$ ./a.out
[ballgame8.C] <main>_<10>  ok 
[ballgame8.C] <main>_<23> Your terminal support color !
[zlll@zlll-pc ballgame]$ 

则说明终端支持显示颜色
