NAME

       glMultiDrawElementsBaseVertex - render multiple sets of primitives by specifying indices
       of array data elements and an index to apply to each index

C SPECIFICATION

       void glMultiDrawElementsBaseVertex(GLenum mode, const GLsizei *count, GLenum type,
                                          const GLvoid * const *indices, GLsizei drawcount,
                                          const GLint *basevertex);

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, indices and basevertex arrays.

       basevertex
           Specifies a pointer to the location where the base vertices are stored.

DESCRIPTION

       glMultiDrawElementsBaseVertex behaves identically to glDrawElementsBaseVertex(), except
       that drawcount separate lists of elements are specifried instead.

       It has the same effect as:

               for (int i = 0; i < drawcount; i++)
                   if (count[i] > 0)
                       glDrawElementsBaseVertex(mode,
                                                count[i],
                                                type,
                                                indices[i],
                                                basevertex[i]);

NOTES

       glMultiDrawElementsBaseVertex is available only if the GL version is 3.1 or greater.

       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.
