Function documentation

static Int Magnum::GL::AbstractObject::maxLabelLength()

Max object label length.

The result is cached, repeated queries don't result in repeated OpenGL calls. If OpenGL 4.3 / OpenGL ES 3.2 is not supported and KHR_debug desktop or ES extension (covered also by ANDROID_extension_pack_es31a) is not available, returns 0. Note that EXT_debug_label has no such limit.
