glRecti function
The glRecti function draws a rectangle.
Syntax
void WINAPI glRecti(
GLint x1,
GLint y1,
GLint x2,
GLint y2
);
Parameters
 x1

The x coordinate of the vertex of a rectangle.
 y1

The y coordinate of the vertex of a rectangle.
 x2

The x coordinate of the opposite vertex of the rectangle.
 y2

The y coordinate of the opposite vertex of the rectangle.
Return value
This function does not return a value.
Error codes
The following error code can be retrieved by the glGetError function.
Name  Meaning 


The function was called between a call to glBegin and the corresponding call to glEnd.

Remarks
The glRecti function supports efficient specification of rectangles as two corner points. Each rectangle command takes four arguments, organized either as two consecutive pairs of (x, y) coordinates, or as two pointers to arrays, each containing an (x, y) pair. The resulting rectangle is defined in the z = 0 plane.
The glRecti(x1, y1, x2, y2) function is exactly equivalent to the following sequence:
glBegin(GL_POLYGON);
glVertex2( x1, y1 );
glVertex2( x2, y1 );
glVertex2( x2, y2 );
glVertex2( x1, y2 );
glEnd( );
Notice that if the second vertex is above and to the right of the first vertex, the rectangle is constructed with a counterclockwise winding.
