/**
|
|
* \file tor_api.h
|
|
* \brief Public C API for the Tor network service.
|
|
*
|
|
* This interface is intended for use by programs that need to link Tor as
|
|
* a library, and launch it in a separate thread. If you have the ability
|
|
* to run Tor as a separate executable, you should probably do that instead
|
|
* of embedding it as a library.
|
|
*
|
|
* To use this API, first construct a tor_main_configuration_t object using
|
|
* tor_main_configuration_new(). Then, you use one or more other function
|
|
* calls (such as tor_main_configuration_set_command_line() to configure how
|
|
* Tor should be run. Finally, you pass the configuration object to
|
|
* tor_run_main().
|
|
*
|
|
* At this point, tor_run_main() will block its thread to run a Tor daemon;
|
|
* when the Tor daemon exits, it will return. See notes on bugs and
|
|
* limitations below.
|
|
*
|
|
* There is no other public C API to Tor: calling any C Tor function not
|
|
* documented in this file is not guaranteed to be stable.

* The command line arguments from tor_main_configuration_set_command_line()

* are taken as if they had been passed to main().
|
|
*
|
|
* This function will not return until Tor is done running. It returns zero
|
|
* on success, and nonzero on failure.
|
|
*
|
|
* If you want to control when Tor exits, make sure to configure a control
|
|
* socket. The OwningControllerFD option may be helpful there.
|
|
*
|
|
* BUG 23847: Sometimes, if you call tor_main a second time (after it has
|
|
* returned), Tor may crash or behave strangely. We have fixed all issues of
|
|
* this type that we could find, but more may remain.
|
|
*
|
|
* LIMITATION: You cannot run more than one instance of Tor in the same
|
|
* process at the same time. Concurrent calls will cause undefined behavior.
|
|
* We do not currently have plans to change this.
|
|
*
|
|
* LIMITATION: While we will try to fix any problems found here, you
|
|
* should be aware that Tor was originally written to run as its own
|
|
* process, and that the functionality of this file was added later. If
|
|
* you find any bugs or strange behavior, please report them, and we'll
|
|
* try to straighten them out.
