The Microsoft-implemented POSIX function names dup and dup2 are deprecated aliases for the _dup and _dup2 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 _dup and _dup2 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.
