Hi everyone,

does anyone know how I can the name of a group in Posix? In C/C++ I can use
getgrgid(), but I just found nothing like this function. Is there any
alternative
to get the name of a group of a file?

Thanks in advance!

Yes that true, it's neither in phobos nor in druntime. Why not using the
C Method? Just declare it as extern(C) and use it ;-).

I too searched and failed to find it. stat_t (defined in 
core.sys.posix.stat.d) has a st_gid field which you could use, but simply 
defining with extern(C) seems to be a better idea.
