<para> <function>initgroups</function> does nothing</para>
<para> <function>chroot</function>, <function>mknod</function>,
<function>settimeofday</function>, and <function>vhangup</function>
always return -1 and sets errno to ENOSYS.</para>
<para> <function>nice</function> allows Cygwin programs to alter their
current runtime priority through the use of its incr argument. Cygwin
processes can be set to IDLE_PRIORITY_CLASS, NORMAL_PRIORITY_CLASS,
HIGH_PRIORITY_CLASS, or REALTIME_PRIORITY_CLASS with the
<function>nice</function> call. NORMAL_PRIORITY_CLASS is the
default. If you pass a positive number to nice(), then the priority
level will decrease by one (within the above list of priorities). A
negative number would make it increase by one. It is not possible to
change it by more than one at a time without making repeated calls.
An increment above REALTIME_PRIORITY_CLASS results in the process
staying at that priority. Likewise, a decrement to
IDLE_PRIORITY_CLASS has it stay at that priority. Note that in the
Win32 API, there are 32 priorities. So currently we only give access
to four of these through <function>nice</function>.</para>
<para> <function>seteuid</function> and <function>setegid</function>
always return 0 and set errno to
ENOSYS.</para>
<para><function>vfork</function> just calls
<function>fork</function></para>
