The Microsoft-implemented POSIX function name
access is a deprecated alias for the _access function. By default, it generates Compiler warning (level 3) C4996. The name is deprecated because it doesn't follow the Standard C rules for implementation-specific names. However, the function is still supported.
We recommend you use _access or the security-enhanced _access_s function instead. Or, you can continue to use this function name, and disable the warning. For more information, see Turn off the warning and POSIX function names.
