getlogin_r and getutxent equivalent in mingw for windows

I am porting my old code from *ix to Windows (on mingw).

A part of the old code contains functionality which gets information about users who logged in from the terminal - using getlogin_r and getutxent functions provided at *ix.

I am not able to find equivalent in 开发者_Python百科MINGW.

Can somebody please help me to find the equivalent in Mingw for windows programming?

Take a look at gnulib, it supports MinGW too (but not all modules are available there).

• getutxent: not available on MinGW
  ("This function is missing on some platforms: Mac OS X 10.3, FreeBSD 6.0, OpenBSD 3.8, Minix 3.1.8, mingw, MSVC 9, BeOS.")
• getlogin_r: available on MinGW
  ("Portability problems fixed by Gnulib: This function is missing on some platforms: NetBSD 3.0, Minix 3.1.8, mingw, MSVC 9.")

As an alternative you can emulate them with Win API.
