mkstemp() implementation for win32

Question

Can anybody point me to the code that implements mkstemp() (C/C++) on Win32, or very close analog.

Must be race-free.

It\'s supposed to look like

You can use _mktemp_s() function, or any of it's variations:

errno_t _mktemp_s(
   char *template,
   size_t sizeInChars
);

where:

• template: File name pattern.
• sizeInChars: Size of the buffer in single-byte characters in _mktemp_s; wide characters in _wmktemp_s, including the null terminator.

It returns 0 on success, and an error code on failure. Note that the function modifyes the template argument.
