NAME

       glDrawRangeElementsBaseVertex - render primitives from array data with a per-element
       offset

C SPECIFICATION

       void glDrawRangeElementsBaseVertex(GLenum mode, GLuint start, GLuint end, GLsizei count,
                                          GLenum type, GLvoid *indices, GLint basevertex);

PARAMETERS

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

       start
           Specifies the minimum array index contained in indices.

       end
           Specifies the maximum array index contained in indices.

       count
           Specifies the number of elements to be rendered.

       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.

       basevertex
           Specifies a constant that should be added to each element of indices when chosing
           elements from the enabled vertex arrays.

DESCRIPTION

       glDrawRangeElementsBaseVertex is a restricted form of glDrawElementsBaseVertex().  mode,
       start, end, count and basevertex match the corresponding arguments to
       glDrawElementsBaseVertex(), with the additional constraint that all values in the array
       indices must lie between start and end, inclusive, prior to adding basevertex. Index
       values lying outside the range [start, end] are treated in the same way as
       glDrawElementsBaseVertex(). The ith element transferred by the corresponding draw call
       will be taken from element indices[i] + basevertex of each enabled array. If the resulting
       value is larger than the maximum value representable by type, 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.

ERRORS

       GL_INVALID_ENUM is generated if mode is not an accepted value.

       GL_INVALID_VALUE is generated if count is negative.

       GL_INVALID_VALUE is generated if end < start.

       GL_INVALID_OPERATION is generated if a geometry shader is active and mode is incompatible
       with the input primitive type of the geometry shader in the currently installed program
       object.

       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.
