NAME
       glGetFramebufferParameter - retrieve a named parameter from a framebuffer

C SPECIFICATION
       void glGetFramebufferParameteriv(GLenum target, GLenum pname, GLint * params);

PARAMETERS
       target
	   The target of the operation, which must be GL_READ_FRAMEBUFFER, GL_DRAW_FRAMEBUFFER or GL_FRAMEBUFFER.

       pname
	   A token indicating the parameter to be retrieved.

       params
	   The address of a variable to receive the value of the parameter named pname.

DESCRIPTION
       glGetFramebufferParameter retrieves the current value of the parameter named pname from the framebuffer bound to target.  target must be
       GL_READ_FRAMEBFUFFER, GL_DRAW_FRAMEBUFFER or GL_FRAMEBUFFER. The token GL_FRAMEBUFFER is treated as GL_DRAW_FRAMEBUFFER. A non-default
       framebuffer must be bound to target.

       pname specifies the parameter to be retrieved. The values retrieved from the framebuffer are written into the variable whose address is
       given by params. The following symbols are accepted in pname:

       GL_FRAMEBUFFER_DEFAULT_WIDTH
	   The value of GL_FRAMEBUFFER_DEFAULT_WIDTH for the framebuffer is written to the single integer variable whose address is given by
	   params.

       GL_FRAMEBUFFER_DEFAULT_HEIGHT
	   The value of GL_FRAMEBUFFER_DEFAULT_HEIGHT for the framebuffer is written to the single integer variable whose address is given by
	   params.

       GL_FRAMEBUFFER_DEFAULT_LAYERS
	   The value of GL_FRAMEBUFFER_DEFAULT_LAYERS for the framebuffer is written to the single integer variable whose address is given by
	   params.

       GL_FRAMEBUFFER_DEFAULT_SAMPLES
	   The value of GL_FRAMEBUFFER_DEFAULT_SAMPLES for the framebuffer is written to the single integer variable whose address is given by
	   params.

       GL_FRAMEBUFFER_DEFAULT_FIXED_SAMPLE_LOCATIONS
	   If the value of GL_FRAMEBUFFER_DEFAULT_FIXED_SAMPLE_LOCATIONS for the framebuffer is GL_TRUE then the single integer variable whose
	   address is in params is set to one, otherwise it is set to zero.

ERRORS
       GL_INVALID_ENUM is generated if target is not one of the accepted framebuffer targets.

       GL_INVALID_ENUM is generated if pname is not one of the accepted parameter names.

       GL_INVALID_OPERATION is generated if the default framebuffer is bound to target.

       params should be the address of a variable to which the client has write access otherwise undefined behavior, including process termination
       may occur.
