.SH "DESCRIPTION"
.PP
\fBglFramebufferRenderbuffer\fR
and
\fBglNamedFramebufferRenderbuffer\fR
attaches a renderbuffer as one of the logical buffers of the specified framebuffer object\&. Renderbuffers cannot be attached to the default draw and read framebuffer, so they are not valid targets of these commands\&.
.PP
For
\fBglFramebufferRenderbuffer\fR, the framebuffer object is that bound to
\fItarget\fR, which must be
\fBGL_DRAW_FRAMEBUFFER\fR,
\fBGL_READ_FRAMEBUFFER\fR
or
\fBGL_FRAMEBUFFER\fR\&.
\fBGL_FRAMEBUFFER\fR
is equivalent to
\fBGL_DRAW_FRAMEBUFFER\fR\&.
.PP
For
\fBglNamedFramebufferRenderbuffer\fR,
\fIframebuffer\fR
is the name of the framebuffer object\&.
.PP
\fIrenderbuffertarget\fR
must be
\fBGL_RENDERBUFFER\fR\&.
.PP
\fIrenderbuffer\fR
must be zero or the name of an existing renderbuffer object of type
\fIrenderbuffertarget\fR\&. If
\fIrenderbuffer\fR
is not zero, then the specified renderbuffer will be used as the logical buffer identified by
\fIattachment\fR
of the specified framebuffer object\&. If
\fIrenderbuffer\fR
is zero, then the value of
\fIrenderbuffertarget\fR
is ignored\&.
.PP
\fIattachment\fR
specifies the logical attachment of the framebuffer and must be
\fBGL_COLOR_ATTACHMENT\fR\fIi\fR,
\fBGL_DEPTH_ATTACHMENT\fR,
\fBGL_STENCIL_ATTACHMENT\fR
or
\fBGL_DEPTH_STENCIL_ATTACHMENT\fR\&.
\fIi\fR
in may range from zero to the value of
\fBGL_MAX_COLOR_ATTACHMENTS\fR
minus one\&. Setting
\fIattachment\fR
to the value
\fBGL_DEPTH_STENCIL_ATTACHMENT\fR
is a special case causing both the depth and stencil attachments of the specified framebuffer object to be set to
\fIrenderbuffer\fR, which should have the base internal format
\fBGL_DEPTH_STENCIL\fR\&.
.PP
The value of
\fBGL_FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE\fR
for the specified attachment point is set to
\fBGL_RENDERBUFFER\fR
and the value of
\fBGL_FRAMEBUFFER_ATTACHMENT_OBJECT_NAME\fR
is set to
\fIrenderbuffer\fR\&. All other state values of specified attachment point are set to their default values\&. No change is made to the state of the renderbuuffer object and any previous attachment to the
\fIattachment\fR
logical buffer of the specified framebuffer object is broken\&.
.PP
If
\fIrenderbuffer\fR
is zero, these commands will detach the image, if any, identified by the specified attachment point of the specified framebuffer object\&. All state values of the attachment point are set to their default values\&.
.SH "ERRORS"
.PP
\fBGL_INVALID_ENUM\fR
is generated by

if
\fItarget\fR
is not one of the accepted framebuffer targets\&.

\fBGL_INVALID_OPERATION\fR
is generated by
\fBglFramebufferRenderbuffer\fR
if zero is bound to
\fItarget\fR\&.
.PP
\fBGL_INVALID_OPERATION\fR
is generated by
\fBglNamedFramebufferRenderbuffer\fR
if
\fIframebuffer\fR
is not the name of an existing framebuffer object\&.
.PP
\fBGL_INVALID_ENUM\fR

\fIattachment\fR
is not one of the accepted attachment points\&.
.PP
\fBGL_INVALID_ENUM\fR
is generated if
\fIrenderbuffertarget\fR
is not
\fBGL_RENDERBUFFER\fR\&.
.PP
\fBGL_INVALID_OPERATION\fR
is generated if
\fIrenderbuffertarget\fR
is not zero or the name of an existing renderbuffer object of type
\fBGL_RENDERBUFFER\fR\&.
