NAME

       glMultiDrawElements - render multiple sets of primitives by specifying indices of array
       data elements

C SPECIFICATION

       void glMultiDrawElements(GLenum mode, const GLsizei * count, GLenum type,
                                const GLvoid * const * indices, GLsizei drawcount);

PARAMETERS

       mode
           Specifies what kind of primitives to render. Symbolic constants GL_POINTS,
           GL_LINE_STRIP, GL_LINE_LOOP, GL_LINES, GL_LINE_STRIP_ADJACENCY, GL_LINES_ADJACENCY,
           GL_TRIANGLE_STRIP, GL_TRIANGLE_FAN, GL_TRIANGLES, GL_TRIANGLE_STRIP_ADJACENCY,
           GL_TRIANGLES_ADJACENCY and GL_PATCHES are accepted.

       count
           Points to an array of the elements counts.

       type
           Specifies the type of the values in indices. Must be one of GL_UNSIGNED_BYTE,
           GL_UNSIGNED_SHORT, or GL_UNSIGNED_INT.

       indices
           Specifies a pointer to the location where the indices are stored.

       drawcount
           Specifies the size of the count and indices arrays.

DESCRIPTION

       glMultiDrawElements specifies multiple sets of geometric primitives with very few
       subroutine calls. Instead of calling a GL function to pass each individual vertex, normal,
       texture coordinate, edge flag, or color, you can prespecify separate arrays of vertices,
       normals, and so on, and use them to construct a sequence of primitives with a single call
       to glMultiDrawElements.

       glMultiDrawElements is identical in operation to glDrawElements() except that drawcount
       separate lists of elements are specified.

       Vertex attributes that are modified by glMultiDrawElements have an unspecified value after
       glMultiDrawElements returns. Attributes that aren't modified maintain their previous
       values.

NOTES

       GL_LINE_STRIP_ADJACENCY, GL_LINES_ADJACENCY, GL_TRIANGLE_STRIP_ADJACENCY and
       GL_TRIANGLES_ADJACENCY are available only if the GL version is 3.2 or greater.

ERRORS

       GL_INVALID_ENUM is generated if mode is not an accepted value.

       GL_INVALID_VALUE is generated if drawcount is negative.

       GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to an enabled
       array or the element array and the buffer object's data store is currently mapped.
