mlockall() and cygwin

mlockall() and cygwin

[Mohamed Amjed Ben Salah]

Hello,
I have a programm that runs very well under Linux. In
this program I use the function mlockall() and i have
a problem to compile it and to run it under cygwin,
because the function mlockall() is not implemented in
the actual version. Have someone idee how to solve
this problem?

Regards
Amjed

mlockall will probably never be implemented since there's no support
for it on user mode level in Win32.  There's support for something like
mlock/munlock, but only on NT and it's also not implemented in Cygwin.

Try building and running without calling mlockall.

Ist it possible to install eposix on cygwin, and then
to use mlockall() ? I saw the documentation of eposix,
and it seems implemented, but I never used eposix.

Er... how is that supposed to work?  eposix is just a library on top
of the underlying OS.  It's an eiffel binding for POSIX routines,
nothing else.  And apart from that, it doesn't even try to implement
mlockall.

POSIX?

Hello,
Is there any similar function in cygwin to avoid
pagging and provide real time ? I have cygwin on Win
XP.

Sorry, no.  If the application is only going to work on NT anyway,
have a look into the MSDN and see the man pages for VirtualLock and
SetProcessWorkingSetSize.

Otherwise, mlock and munlock still have to be implemented in Cygwin
(http://cygwin.com/acronyms/#SHTDI), mlockall/munlockall probably
never will.
