What toolkit are you using ?

Assuming you're using GLUT, here's a minimalistic example.

    
#include <GL/glut.h>

void
DisplayMain()
{
glClear( GL_COLOR_BUFFER_BIT );
// your drawing code here

glFinish();
glutSwapBuffers();
}

void
ReshapeMain( int w, int h)
{
glViewport( 0, 0, w, h );
// Adjust your projection matrix to your new window size

}

void
Idle()
{
// Animation, AI ..

glutPostRedisplay();
}

void
main( int argc, char** argv )
{
glutInit( &argc, argv );
glutInitDisplayFunc( GLUT_RGB | GLUT_DOUBLE );
glutCreateWindow( argv[0] );
glutDisplayFunc( DisplayMain );
glutReshapeFunc( ReshapeMain );
glutIdleFunc( Idle );

glutMainLoop();
}
