Subject: Re: Win98se and using SSHD as a TRUE service

The idea here is to have SSHD start as a true service in Win9x such that it
will NOT dies when a user logs out.  To do this the process must make the
system call "RegisterServiceProcess" which only exist in Win95, Win98 and
WinMe.

James Coleman:  I tryied adding the #include "windows.h" line but I still
have compile errors:

$ make
gcc -g -O2 -Wall -Wpointer-arith -Wno-uninitialized -I. -I.. -I. -I./..  -DH
AVE_CONFIG_H -c daemon.c
daemon.c: In function `daemon':
daemon.c:67: parse error before `kerneldll'
daemon.c:68: `kerneldll' undeclared (first use in this function)
daemon.c:68: (Each undeclared identifier is reported only once
daemon.c:68: for each function it appears in.)
daemon.c:72: parse error before `('
daemon.c:73: `RegisterService' undeclared (first use in this function)
daemon.c:79: `RegisterService' used prior to declaration
daemon.c:79: warning: implicit declaration of function `RegisterService'
make: *** [daemon.o] Error 1

The source is at the end of this email.

The problem may be easy to spot but its beyond me.

I am trying to fix the right file for this right?

Thanks for any help,
Gérald
