GLFRAMEBUFFERPARAMET(3G)        [FIXME: manual]       GLFRAMEBUFFERPARAMET(3G)

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.
