Hi all

I need to find equivalent windows libraries for the following unix
ones.

#include <sys/prctl.h>
#include <sys/ioctl.h>
#include <unistd.h>

Basically I need to use the sproc() function in sys/prctl.h. The
sys/ioctl.h and  unistd.h libraries are very necessary though. Are
there any windows versions of these libraries

Thank you

That exact functionality is very *VERY* unlikely to exist
on windows. They may or may not be something similar with
a completely different API.

Again ioctls are a unix concept and don't exist on windows.

Much of the stuff in <unistd.h> does exist on windows and
some of it works very very badly. For instance windows
does have 64 bit offset version of open/read/write/lseek
etc but they have seriously egregious bugs.

These are not libraries they are header files defining
the workings of what is basically libc.

Everyone seems to assume that the current system in America is capitalism.
I beg to differ. True capitalism does not involve false advertising,
distribution cartels, or political lobbying for special advantages in the
market. How can you call Microsoft or the RIAA capitalist, when their main
business is interfering with a free market? Some of us would like to see a
*return* to capitalism in this country. - Jim Flynn on Linuxtoday.com

ISTR the pthreads library exists for win32. The best strategy then would
be to convert the sproc calls to pthreads on unix first, then on win32
(rather than ifdef-ing to use sproc on unix and something else on win32).

I'm interested, having just hit several largefile problems with our
applications. Details? (of both how to call them and what the known bugs
are!) TIA.

Grab the sources to libsndfile:

http://www.mega-nerd.com/libsndfile/#Download

In particular, the stuff that doesn't work is the 64 bit offset
versions of lseek and fstat. The program tests/win32_test.c in
the tarball details this in all its glory. I've just tried this
on winxp and it works correctly. It failed on win98 and/or win2k.

In the end, the only way I could get correctly working large
file stuff working on windows was to wrap the native win32
API functions CreateFile/WriteFile/SetFilePointer to create
similar functoins to the POSIX ones. This is all in the file
src/file_io.c of the above tarball.

The Win32 API functions work, but should be used as prime
example of how not to design an API (likewise for the rest
of the win32 API).

I forgot to mention that im using Microsoft VC++ as my compiler (yes i
have to use this...)

Is there something similar that i can use in windows?

Are you referring to the winsock.h header?

I don't believe that there is anything even remotely similar.

No.

Ioctls are often incompatible across difference unices.

Cygwin probably does have some common icotls but is unlikely
to have all of the one you would expect on your unix of
choice.
