j0, j1, jn

The Microsoft-implemented POSIX function names j0, j1, and jn are deprecated aliases for the _j0, _j1, and _jn functions. By default, they generate Compiler warning (level 3) C4996. The names are deprecated because they don't follow the Standard C rules for implementation-specific names. However, the functions are still supported.

We recommend you use _j0, _j1, and _jn instead. Or, you can continue to use these function names, and disable the warning. For more information, see Turn off the warning and POSIX function names.
