fglClearColor(3G)

NAME
     fglClearColor - specify clear values for the color buffers


FORTRAN SPECIFICATION
     SUBROUTINE fglClearColor( REAL*4 red,
                               REAL*4 green,
                               REAL*4 blue,
                               REAL*4 alpha )


PARAMETERS
     red, green, blue, alpha
                           Specify the red, green, blue, and alpha values used
                           when the color buffers are cleared.  The initial
                           values are all 0.

DESCRIPTION
     fglClearColor specifies the red, green, blue, and alpha values used by
     fglClear to clear the color buffers.  Values specified by fglClearColor
     are clamped to the range [0, 1].

ERRORS
     GL_INVALID_OPERATION is generated if fglClearColor is executed between
     the execution of fglBegin and the corresponding execution of fglEnd.

ASSOCIATED GETS
     fglGet with argument GL_COLOR_CLEAR_VALUE
