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.
