NAME

       glFramebufferParameteri, glNamedFramebufferParameteri - set a named parameter of a
       framebuffer object

C SPECIFICATION

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

       void glNamedFramebufferParameteri(GLuint framebuffer, GLenum pname, GLint param);

PARAMETERS

       target
           Specifies the target to which the framebuffer is bound for glFramebufferParameteri.

       framebuffer
           Specifies the name of the framebuffer object for glNamedFramebufferParameteri.

       pname
           Specifies the framebuffer parameter to be modified.

       param
           The new value for the parameter named pname.

DESCRIPTION

       glFramebufferParameteri and glNamedFramebufferParameteri modify the value of the parameter
       named pname in the specified framebuffer object. There are no modifiable parameters of the
       default draw and read framebuffer, so they are not valid targets of these commands.

       For glFramebufferParameteri, the framebuffer object is that bound to target, which must be
       GL_DRAW_FRAMEBUFFER, GL_READ_FRAMEBUFFER or GL_FRAMEBUFFER.  GL_FRAMEBUFFER is equivalent
       to GL_DRAW_FRAMEBUFFER.

       For glNamedFramebufferParameteri, framebuffer is the name of the framebuffer object.

       pname specifies the parameter to be modified. The following values are accepted:

       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 by glFramebufferParameteri if target is not one of the
       accepted framebuffer targets.

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

       GL_INVALID_OPERATION is generated by glNamedFramebufferParameteri if framebuffer is not
       the name of an existing framebuffer object.

       GL_INVALID_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_INVALID_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_INVALID_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_INVALID_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.
