\fIstart\fR

.RE
.PP
\fIend\fR
.RS 4
Specifies the maximum array index contained in

.PP
\fIcount\fR
.RS 4
Specifies the number of elements to be rendered\&.
.RE
.PP
\fItype\fR
.RS 4
Specifies the type of the values in indices\&. Must be one of
\fBGL_UNSIGNED_BYTE\fR,
\fBGL_UNSIGNED_SHORT\fR, or
\fBGL_UNSIGNED_INT\fR\&.
.RE
.PP
\fIindices\fR
.RS 4
Specifies a pointer to the location where the indices are stored\&.

\fIbasevertex\fR
.RS 4
Specifies a constant that should be added to each element of

.SH "DESCRIPTION"
.PP
\fBglDrawRangeElementsBaseVertex\fR
is a restricted form of
\fBglDrawElementsBaseVertex\fR()\&.
\fImode\fR,
\fIstart\fR,
\fIend\fR,
\fIcount\fR
and
\fIbasevertex\fR
match the corresponding arguments to
\fBglDrawElementsBaseVertex\fR(), with the additional constraint that all values in the array
\fIindices\fR
must lie between
\fIstart\fR
and
\fIend\fR, inclusive, prior to adding
\fIbasevertex\fR\&. Index values lying outside the range [\fIstart\fR,
\fIend\fR] are treated in the same way as
\fBglDrawElementsBaseVertex\fR()\&. The
\fIi\fRth element transferred by the corresponding draw call will be taken from element
\fIindices\fR[i] +
\fIbasevertex\fR
of each enabled array\&. If the resulting value is larger than the maximum value representable by
\fItype\fR, it is as if the calculation were upconverted to 32\-bit unsigned integers (with wrapping on overflow conditions)\&. The operation is undefined if the sum would be negative\&.
.SH "ERRORS"
.PP
\fBGL_INVALID_ENUM\fR
is generated if
\fImode\fR
is not an accepted value\&.
.PP
\fBGL_INVALID_VALUE\fR
is generated if
\fIcount\fR
is negative\&.
.PP
\fBGL_INVALID_VALUE\fR
is generated if
\fIend\fR
<
\fIstart\fR\&.
.PP
\fBGL_INVALID_OPERATION\fR
is generated if a geometry shader is active and
\fImode\fR
is incompatible with the input primitive type of the geometry shader in the currently installed program object\&.
.PP
\fBGL_INVALID_OPERATION\fR
is generated if a non\-zero buffer object name is bound to an enabled array or the element array and the buffer object\*(Aqs data store is currently mapped\&.
