No, you don't ;)

Try rather to tell us what you want to achive, not everyone
knows what kernel32.dll is or provides.

My group "PORTEX" is working on converting PE File format to ELF file
format. we need to implement kernel32.dll file functions like
heapcreat , heapdestroy , malloc , valloc etc. on linux . does linux
have equivalent fuctions ?

Regards.

It depends on the function, of course.

- malloc() is a standard C function, supported by glibc under Linux
- valloc() is a BSD function, supported by glibc under Linux
- heapcreat, heapdestroy, etc, aren't /directly/ supported in Linux, but
(depending on what they do on MSWindows) /may/ have Linux equivalents with
different names. My guess is that they refer to multithreaded memory
management, which is usually covered by the posix_threads library.

You really need to pick up some manuals on porting from Windows to Unix, or
use a porting library (like winelib or vxWindows).

See the wine project, www.winehq.org , though you _are_ trying to
run binaries on another OS than it was created for. That will
seldom be 100% stable and ok.
Linux have malloc and friends, tough not direct equivialents to
heapcreat/destroy.
I suggest you take a deeper look at linux and see what it provides.
e.g. http://www.gnu.org/software/libc/manual/
and the Single Unix Specification, which linux implement
lots of. http://www.unix-systems.org/version3/online.html

Read the Wine source. They have probably done what you want to do.

Linux does have equivalent functions, but they are not the same for obvious
reasons. Once again, Wine has done this already. If you're porting a
filesystem, having the Win32 kernel functions won't help. You'll need to
port to equivalent functions under Linux and understand how Linux handles
filesytems (which isn't trivial, you'll need to spend some time with this).
There are enough filesystems that you can view the source for that this
isn't impossible to do without porting Win32 specific kernel functions.
Basically, you can't just move the Win32 kernel into Linux and expect the
filesystem you have written to work in any meaningful way.
