.SH "NAME"
glMultiDrawElementsBaseVertex \- render multiple sets of primitives by specifying indices of array data elements and an index to apply to each index
.SH "C SPECIFICATION"
.HP \w'void\ glMultiDrawElementsBaseVertex('u
.BI "void glMultiDrawElementsBaseVertex(GLenum\ " "mode" ", const\ GLsizei\ *" "count" ", GLenum\ " "type" ", const\ GLvoid\ *\ const\ *" "indices" ", GLsizei\ " "drawcount" ", const\ GLint\ *" "basevertex" ");"
.SH "PARAMETERS"
.PP
\fImode\fR
.RS 4
Specifies what kind of primitives to render\&. Symbolic constants
\fBGL_POINTS\fR,
\fBGL_LINE_STRIP\fR,
\fBGL_LINE_LOOP\fR,
\fBGL_LINES\fR,
\fBGL_LINE_STRIP_ADJACENCY\fR,
\fBGL_LINES_ADJACENCY\fR,

are accepted\&.
.RE
.PP
\fIcount\fR
.RS 4
Points to an array of the elements counts\&.
.RE
.PP
\fItype\fR
.RS 4
Specifies the type of the values in
\fIindices\fR\&. 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\&.
.RE
.PP
\fIdrawcount\fR
.RS 4
Specifies the size of the
\fIcount\fR,
\fIindices\fR
and
\fIbasevertex\fR
arrays\&.
.RE
.PP
\fIbasevertex\fR
.RS 4
Specifies a pointer to the location where the base vertices are stored\&.
.RE
.SH "DESCRIPTION"
.PP
\fBglMultiDrawElementsBaseVertex\fR
behaves identically to
\fBglDrawElementsBaseVertex\fR(), except that
\fIdrawcount\fR
separate lists of elements are specifried instead\&.
.PP
It has the same effect as:
.sp
.if n \{\
.RS 4
.\}
.nf
    for (int i = 0; i < \fIdrawcount\fR; i++)
        if (\fIcount\fR[i] > 0)
            glDrawElementsBaseVertex(\fImode\fR,
                                     \fIcount\fR[i],
                                     \fItype\fR,
                                     \fIindices[i]\fR,
                                     \fIbasevertex[i]\fR);

.SH "NOTES"
.PP
\fBglMultiDrawElementsBaseVertex\fR
is available only if the GL version is 3\&.1 or greater\&.
.PP
\fBGL_LINE_STRIP_ADJACENCY\fR,
\fBGL_LINES_ADJACENCY\fR,
\fBGL_TRIANGLE_STRIP_ADJACENCY\fR
and
\fBGL_TRIANGLES_ADJACENCY\fR
are available only if the GL version is 3\&.2 or greater\&.
.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
\fIdrawcount\fR
is negative\&.
.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\&.
