Defines a list of color index arrays.
OpenGL C bindings library: libGL.a
void glIndexPointerListIBM( GLenum type, GLint stride, const GLvoid **pointer, GLint ptrstride)
The glIndexPointerListIBM subroutine specifies the location and data format of a list of arrays of color indices to use when rendering. The type parameter specifies the data type of each color index. The stride parameter gives the byte stride from one color index to the next allowing vertices and attributes to be packed into a single array or stored in separate arrays. (Single-array storage may be more efficient on some implementations; see glInterleavedArrays). The ptrstride parameter specifies the byte stride from one pointer to the next in the pointer array.
When a color index array is specified, type, stride, pointer and ptrstride are saved as client side state.
A stride value of 0 does not specify a "tightly packed" array as it does in glIndexPointer. Instead, it causes the first array element of each array to be used for each vertex. Also, a negative value can be used for stride, which allows the user to move through each array in reverse order.
To enable and disable the color index arrays, call glEnableClientState and glDisableClientState with the argument GL_INDEX_ARRAY. The color index array is initially disabled. When enabled, the color index arrays are used when glMultiDrawArraysEXT, glMultiDrawElementsEXT, glMultiModeDrawArraysIBM, glMultiModeDrawElementsIBM, glDrawArrays, glDrawElements or glArrayElement is called. The last three calls in this list will only use the first array (the one pointed at by pointer[0]). See the descriptions of these routines for more information on their use.
The glIndexPointerListIBM subroutine is available only if the GL_IBM_vertex_array_lists extension is supported.
Execution of glIndexPointerListIBM is not allowed between glBegin and the corresponding glEnd, but an error may or may not be generated. If an error is not generated, the operation is undefined.
The glIndexPointerListIBM subroutine is typically implemented on the client side.
Since the color index array parameters are client side state, they are not saved or restored by glPushAttrib and glPopAttrib. Use glPushClientAttrib and glPopClientAttrib instead.
When a glIndexPointerListIBM call is encountered while compiling a display list, the information it contains does NOT contribute to the display list, but is used to update the immediate context instead.
The glIndexPointer call and the glIndexPointerListIBM call share the same state variables. A glIndexPointer call will reset the color index list state to indicate that there is only one color index list, so that any and all lists specified by a previous glIndexPointerListIBM call will be lost, not just the first list that it specified.
GL_INVALID_ENUM is generated if type is not an accepted value.
