Egl documentation states:
If binding context would exceed the number of current contexts of that client API type supported by the implementation, an EGL_BAD_ACCESS error is generated.
https://www.khronos.org/registry/EGL/sdk/docs/man/html/eglMakeCurrent.xhtml
So is there any way to query "number of current contexts of that client API type supported"?
or is it provided by graphic vendors manually? (e.g driver specification)
