Sure, but in any perl API?

There's apparently a new libwin32@perl.org list,
the perl-win32-porters@listserv.ActiveState.com list is almost 
unmaintained for some years now.

We will check out there where this cygwin specific functionality
will go to.
Win32::Process::CygwinToWin32ProcessID() is my suggestion.

.pm:
=item Win32::Process::CygwinToWin32ProcessID($pid)

Returns the windows process ID for the given cygwin pid.
On non-cygwin platforms it will return the $pid argument without 
translation.

=item Win32::Process::Win32ToCygwinProcessID($pid)

Returns the cygwin process ID for the given windows pid.
On non-cygwin platforms it will return the $pid argument without 
translation.

.xs:
DWORD
CygwinToWin32ProcessID(pid)
    DWORD pid
CODE:
#ifdef __CYGWIN__
    RETVAL = cygwin_internal(CW_CYGWIN_PID_TO_WINPID, pid);
#else
    RETVAL = pid;
#endif
OUTPUT:
    RETVAL

DWORD
Win32ToCygwinProcessID(pid)
    DWORD pid
CODE:
#ifdef __CYGWIN__
    RETVAL = (DWORD)cygwin32_winpid_to_pid(pid);
#else
    RETVAL = pid;
#endif
OUTPUT:
    RETVAL
