NAME

       glFramebufferParameteri - set a named parameter of a framebuffer

C SPECIFICATION

       void glFramebufferParameteri(GLenum target, GLenum pname, GLint param);

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 modified.

       param
	   The new value for the parameter named pname.

DESCRIPTION

       glFramebufferParameteri modifies the current value of the parameter named pname in 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 modified. The following symbols are accepted in pname:

       GL_FRAMEBUFFER_DEFAULT_WIDTH
	   param specifies the assumed with for a framebuffer object with no attachments. If a framebuffer has attachments then the width of those
	   attachments is used, otherwise the value of GL_FRAMEBUFFER_DEFAULT_WIDTH is used for the framebuffer.  param must be greater than or
	   equal to zero and less than or equal to the value of GL_MAX_FRAMEBUFFER_WIDTH.

       GL_FRAMEBUFFER_DEFAULT_HEIGHT
	   param specifies the assumed height for a framebuffer object with no attachments. If a framebuffer has attachments then the height of
	   those attachments is used, otherwise the value of GL_FRAMEBUFFER_DEFAULT_HEIGHT is used for the framebuffer.  param must be greater
	   than or equal to zero and less than or equal to the value of GL_MAX_FRAMEBUFFER_HEIGHT.

       GL_FRAMEBUFFER_DEFAULT_LAYERS
	   param specifies the assumed number of layers for a framebuffer object with no attachments. If a framebuffer has attachments then the
	   layer count of those attachments is used, otherwise the value of GL_FRAMEBUFFER_DEFAULT_LAYERS is used for the framebuffer.	param must
	   be greater than or equal to zero and less than or equal to the value of GL_MAX_FRAMEBUFFER_LAYERS.

       GL_FRAMEBUFFER_DEFAULT_SAMPLES
	   param specifies the assumed number of samples in a framebuffer object with no attachments. If a framebuffer has attachments then the
	   sample count of those attachments is used, otherwise the value of GL_FRAMEBUFFER_DEFAULT_SAMPLES is used for the framebuffer.  param
	   must be greater than or equal to zero and less than or equal to the value of GL_MAX_FRAMEBUFFER_SAMPLE.

       GL_FRAMEBUFFER_DEFAULT_FIXED_SAMPLE_LOCATIONS
	   param specifies whether the framebuffer should assume identical sample locations and the same number of samples for all texels in the
	   virtual image. If param is zero, then the implementation may vary the position or the count of samples within the virtual image from
	   pixel to pixel, otherwise it will use the same sample position and count for all pixels in the virtual image.

ERRORS

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

       GL_INVAILD_VALUE is generated if pname is GL_FRAMEBUFFER_DEFAULT_WIDTH and param is less than zero or greater than the value of
       GL_MAX_FRAMEBUFFER_WIDTH.

       GL_INVAILD_VALUE is generated if pname is GL_FRAMEBUFFER_DEFAULT_HEIGHT and param is less than zero or greater than the value of
       GL_MAX_FRAMEBUFFER_HEIGHT.

       GL_INVAILD_VALUE is generated if pname is GL_FRAMEBUFFER_DEFAULT_LAYERS and param is less than zero or greater than the value of
       GL_MAX_FRAMEBUFFER_LAYERS.

       GL_INVAILD_VALUE is generated if pname is GL_FRAMEBUFFER_DEFAULT_SAMPLES and param is less than zero or greater than the value of
       GL_MAX_FRAMEBUFFER_SAMPLES.

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