| + | |||
| + | ====Syntax of closegraph ==== | ||
| + | <code c> | ||
| + | #include <graphics.h> | ||
| + | void closegraph(int wid=ALL_WINDOWS); | ||
| + | </code> | ||
| + | |||
| + | |||
| + | ==== Description of closegraph ==== | ||
| + | <code c> | ||
| + | closegraph deallocates all memory allocated by the graphics system, then | ||
| + | restores the screen to the mode it was in before you called initgraph. | ||
| + | (The graphics system deallocates memory, such as the drivers, fonts, and | ||
| + | an internal buffer, through a call to _graphfreemem.) | ||
| + | </code> | ||
| + | |||
| + | |||
| + | ==== Example of closegraph ==== | ||
| + | <code c> | ||
| + | /* closegraph example */ | ||
| + | |||
| + | #include <graphics.h> | ||
| + | #include <stdlib.h> | ||
| + | #include <stdio.h> | ||
| + | #include <conio.h> | ||
| + | |||
| + | int main(void) | ||
| + | { | ||
| + | /* request autodetection */ | ||
| + | int gdriver = DETECT, gmode, errorcode, x, y; | ||
| + | |||
| + | /* initialize graphics mode */ | ||
| + | initgraph(&gdriver, &gmode, ""); | ||
| + | |||
| + | /* read result of initialization */ | ||
| + | errorcode = graphresult(); | ||
| + | |||
| + | if (errorcode != grOk) { /* an error occurred */ | ||
| + | printf("Graphics error: %s\n", grapherrormsg(errorcode)); | ||
| + | printf("Press any key to halt:"); | ||
| + | |||
| + | getch(); | ||
| + | exit(1); /* terminate with an error code */ | ||
| + | } | ||
| + | |||
| + | x = getmaxx() / 2; | ||
| + | y = getmaxy() / 2; | ||
| + | |||
| + | /* output a message */ | ||
| + | settextjustify(CENTER_TEXT, CENTER_TEXT); | ||
| + | outtextxy(x, y, "Press a key to close the graphics system:"); | ||
| + | |||
| + | getch(); /* wait for a key */ | ||
| + | /* closes down the graphics system */ | ||
| + | closegraph(); | ||
| + | printf("We're now back in text mode.\n"); | ||
| + | printf("Press any key to halt:"); | ||
| + | getch(); | ||
| + | return 0; | ||
| + | |||
| + | } | ||
