<para><function>chroot</function> only emulates a chroot function call
|
|
by keeping track of the current root and accomodating this in the file
|
|
related function calls. A real chroot functionality is not supported by
|
|
Windows however.</para>
|
|
|
|
<para><function>clock_nanosleep</function> currently supports only
|
|
CLOCK_REALTIME and CLOCK_MONOTONIC. <function>clock_setres</function>,
|
|
<function>clock_settime</function>, and <function>timer_create</function>
|
|
currently support only CLOCK_REALTIME.</para>
|
|
|
|
<para>POSIX file locks via <function>fcntl</function> or
|
|
<function>lockf</function>, as well as BSD <function>flock</function> locks
|
|
are advisory locks. They don't interact with Windows mandatory locks, nor
|
|
do POSIX fcntl locks interfere with BSD flock locks or vice versa.</para>
|
|
|
|
<para>BSD file locks created via <function>flock</function> are only
|
|
propagated to the direct parent process, not to grand parents or sibling
|
|
processes. The locks are only valid in the creating process, its parent
|
|
process, and subsequently started child processes sharing the same file
|
|
descriptor.</para>
|
|
|
|
<para>In very rare circumstances an application would want to use Windows
|
|
mandatory locks to interact with non-Cygwin Windows processes accessing the
|
|
same file (databases, etc). For these purposes, the entire locking mechanism
|
|
(fcntl/flock/lockf) can be switched to Windows mandatory locks on a
|
|
per-descriptor/per-process basis. For this purpose, use the call
|
|
|
|
<screen>
|
|
fcntl (fd, F_LCK_MANDATORY, 1);
|
|
</screen>
|
|
|
|
After that, all file locks on this descriptor will follow Windows mandatory
|
|
record locking semantics: Locks are per-descriptor/per-process; locks are not
|
|
propagated to child processes, not even via <function>execve</function>;
|
|
no atomic replacement of read locks with write locks and vice versa on the
|
|
same descriptor; locks have to be unlocked exactly as they have been locked.

<para><function>getitimer</function> and <function>setitimer</function>

<para><function>link</function> will fail on FAT, FAT32, and other filesystems

not supporting hardlinks, just as on Linux.</para>

|
<para><function>lseek</function> only works properly on files opened in

|
binary mode. On files opened in textmode (via mount mode or explicit
|
|
open flag) its positioning is potentially unreliable.</para>
|
|
|
|
<para><function>setuid</function> is only safe against reverting the user
|
|
switch after a call to one of the exec(2) functions took place. Windows
|
|
doesn't support a non-revertable user switch within the context of Win32
|
|
processes.</para>

<para><function>vfork</function> just calls <function>fork</function>.</para>

<para><function>vhangup</function> and <function>revoke</function> always

return -1 and set errno to ENOSYS. <function>grantpt</function> and
