Do not attempt to close streams not opened by fopen (includes _wfopen) or [fopen_s] (includes wfopen_s).

Opens a file. These versions of fopen and _wfopen have security enhancements, as described in Security Features in the CRT [https://msdn.microsoft.com/en-us/library/8ef0s5kh.aspx].

public static extern Int32 fopen_s(out IntPtr pFile, String filename, String mode);

public static extern Int32 _wfopen_s(out IntPtr pFile, String filename, String mode);

Public Shared Function fopen_s(ByRef pFile As IntPtr, ByVal filename As String, ByVal mode As String) As Int32

Public Shared Function _wfopen_s(ByRef pFile As IntPtr, ByVal filename As String, ByVal mode As String) As Int32

It is advisable to use _wfopen_s whenever possible. fopen_s supports Unicode but requires additional "help"; you must add a "ccs=encoding" parameter to the mode parameter. Valid encoding values are UNICODE, UTF-8, and UTF-16LE; if ccs is not provided, fopen_s falls back to ASCII (it is unknown what happens if an invalid value is passed).

if (!fopen_s(out file, "example.txt", "w, ccs=UNICODE"))

if (!_wfopen_s(out file, "example.txt", "w"))

[fopen] (includes _wfopen)

[fopen_s] on MSDN

freopen tries to close any file already associated with the stream given as third parameter and disassociates it. Then, whether that stream was successfuly closed or not, freopen opens the file whose name is passed in the first parameter, filename, and associates it with the specified stream just as fopen would do using the mode value specified as the second parameter.
