@item
This function is unsafe to call between @code{fork} and @code{exec} if
the parent process is multi-threaded. Instead, use @code{getgroups} or
@code{getgrouplist} (or use the gnulib module @code{mgetgroups})
before forking, and @code{setgroups} in the child.
@item
This function is missing on some platforms:
mingw, MSVC 14.
