寫檔案

#include <stdio.h>

FILE *fout=NULL, *fin=NULL;

int main(int argc,char**argv)

{

    if(fout==NULL)

        fout=fopen("output.txt","w+");

    fprintf(fout,"Hello World\n");

    return 0;

}

#include <GL/glut.h>
#include <stdio.h>
FILE *fout=NULL, *fin=NULL;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
    glutSolidTeapot(0.3);
    glutSwapBuffers();
}
void motion(int x,int y)
{
    if(fout==NULL)
        fout=fopen("motion.txt","w+");
    fprintf(fout,"%d %d\n",x,y);
    printf("%d %d\n",x,y);
}



int main(int argc,char**argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    glutCreateWindow("3D");
    glutDisplayFunc(display);
    glutMotionFunc(motion);
    glutMainLoop();
}

可以將滑鼠做標寫入檔案中
