* File : $Source: /cvsroot/ijbswa/current/w32svrapi.c,v $
|
||
*
|
||
* Purpose : Win32 Services API for Privoxy.
|
||
* Provides the implementation of an Win32 service to
|
||
* allow the code to directly register and run as a
|
||
* native Windows service application.
|
||
*
|
||
* Since Win9x/ME platforms don't provide or support
|
||
* running programs as services, this code uses runtime
|
||
* loading and calling of the Win32 Service API, to
|
||
* prevent the possibility of getting "entry point not
|
||
* found" type errors on unsupported platforms. This adds
|
||
* a little more complexity to the code, but it is worth
|
||
* doing to provide that isolation.
