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.
