.RE
.SH "DESCRIPTION"
.PP
\fBglGetRenderbufferParameteriv\fR
and
\fBglGetNamedRenderbufferParameteriv\fR
query parameters of a specified renderbuffer object\&.
.PP
For
\fBglGetRenderbufferParameteriv\fR, the renderbuffer object is that bound to
\fItarget\fR, which must be
\fBGL_RENDERBUFFER\fR\&.
.PP
For
\fBglGetNamedRenderbufferParameteriv\fR,
\fIrenderbuffer\fR
is the name of the renderbuffer object\&.
.PP
Upon successful return,
\fIparam\fR
will contain the value of the renderbuffer parameter specified by
\fIpname\fR, as described below\&.
.PP
\fBGL_RENDERBUFFER_WIDTH\fR, \fBGL_RENDERBUFFER_HEIGHT\fR, \fBGL_RENDERBUFFER_INTERNAL_FORMAT\fR or \fBGL_RENDERBUFFER_SAMPLES\fR
.RS 4
\fIparams\fR
returns the width in pixels, the height in pixels, internal format, or the number of samples, respectively, of the image of the specified renderbuffer object\&.
.RE
.PP
\fBGL_RENDERBUFFER_RED_SIZE\fR, \fBGL_RENDERBUFFER_GREEN_SIZE\fR, \fBGL_RENDERBUFFER_BLUE_SIZE\fR, \fBGL_RENDERBUFFER_ALPHA_SIZE\fR, \fBGL_RENDERBUFFER_DEPTH_SIZE\fR or \fBGL_RENDERBUFFER_STENCIL_SIZE\fR
.RS 4
\fIparams\fR
returns the actual resolution in bits (not the resolution specified when the image was defined) for the red, green, blue, alpha, depth or stencil components, respectively, of the image of the renderbuffer object\&.
.RE
.SH "ERRORS"
.PP
\fBGL_INVALID_ENUM\fR
is generated by
\fBglGetRenderbufferParameteriv\fR
if
\fItarget\fR
is not
\fBGL_RENDERBUFFER\fR\&.
.PP
\fBGL_INVALID_OPERATION\fR
is generated by
\fBglGetRenderbufferParameteriv\fR
if zero is bound to
\fItarget\fR\&.
.PP
\fBGL_INVALID_OPERATION\fR
is generated by
\fBglGetNamedRenderbufferParameteriv\fR
if
\fIrenderbuffer\fR
is not the name of an existing renderbuffer object\&.
.PP
\fBGL_INVALID_ENUM\fR
is generated if
\fIpname\fR
is not one of the accepted parameter names described above\&.
