# Controlling the BOINC client via RPC
|
||||
|
||||
The BOINC client provides a set of RPCs (remote procedure calls)
|
||||
for control and state interrogation.
|
||||
This enables the development of GUI (graphical user interface) programs.
|
||||
These RPCs send XML request and reply messages over a TCP connection.
|
||||
The XML formats are not documented, but can be inferred from the source code.
|
||||
The XML formats are documented in [GuiRpcProtocol](GuiRpcProtocol).
|
||||
|
||||
The following bindings are available:
|
||||
|
||||
* BOINC has a C++ binding, consisting of the GUI_RPC class.
|
||||
The interface is in [lib/gui_rpc_client.h](source:boinc-v2/lib/gui_rpc_client.h),
|
||||
and the program [boinc_cmd.cpp](source:boinc-v2/client/boinc_cmd.cpp)
|
||||
* BOINC has a C++ binding, consisting of the RPC_CLIENT class.
|
||||
The interface is in
|
||||
[lib/gui_rpc_client.h](https://github.com/BOINC/boinc/blob/master/lib/gui_rpc_client.h),
|
||||
and the program
|
||||
[boinc_cmd.cpp](https://github.com/BOINC/boinc/blob/master/client/boinc_cmd.cpp)
|
||||
gives a usage example.
|
||||
All member functions return an integer error code.
|
||||
* Another C++ binding is part of [boinctui](https://code.google.com/p/boinctui/).

# Connecting
|

## Connecting
|
||||
|
||||
To establish RPC connection to a host,
|
||||
create a `RPC_CLIENT` object and call
|
||||
|
||||
`init(char* host)`.
|
||||
|
||||
To establish an RPC connection to a host:
|
||||
|
||||
# Dealing with versions
|
||||
```
|
||||
RPC_CLIENT rpc;
|
||||
rpc.init(char* host)
|
||||
```
|
||||
|
||||
## Dealing with versions
|
||||
|
||||
The GUI RPC protocol changes over time.
|
||||
If you're writing a GUI program that needs to communicate with older
|
||||
versions of the BOINC client:
|
||||
```
|
||||
exchange_versions("your program name", VERSION_INFO& v));
|
||||
```
|
||||
The client's version is returned in v.
|
||||
Use the client version number to decide what subsequent RPCs to make
|
||||
(some version info is included in the RPC list below).
|
||||
|
||||
* Call `exchange_versions()` to get the client version.
|
||||
* If `exchange_versions()` fails (it's not supported in pre-5.6 clients)
|
||||
do a `get_state()` RPC, and get the client version from `CC_STATE::version_info`.
|
||||
* Use the client version number to decide what subsequent RPCs to make
|
||||
(version info is included in the RPC list below).
|
||||
## Authorization

#!comment

Most RPCs on the list *lack* version information saying since when they're available.

# Authorization
|
||||
|
||||
The RPC protocol allows the GUI program to authenticate itself using a password.
|
||||
The RPC protocol allows the GUI program to authenticate itself using a
|
||||
[password](https://boinc.berkeley.edu/wiki/Controlling_BOINC_remotely).
|
||||
Some of the RPC operations can be done without authentication;
|
||||
others can be done without authentication,
|
||||
but only by a GUI program running on the same machine.
|
||||
|
||||
`authorize(char* password)`::
|
||||
Do authorization sequence with the peer, using given password.
|
||||
```
|
||||
retval = rpc.authorize(char* password)
|
||||
```
|
||||
Authorize with the peer, using given password.

# RPC list

||||
all functions except `get_state()`,
|
||||
`get_results()`, `get_screensaver_mode()`,
|
||||
and `set_screensaver_mode()` require authorization.
|
||||
|
||||
|
||||
#!comment
|
||||
A few function headers like set_screensaver_mode, project_attach and acct_mgr_rpc have the `monospaced`
|
||||
parts broken that way to allow word wrap.

|
||||
rpc.read_global_prefs_override();
|
||||
|

`set_proxy_settings(PROXY_INFO&)`::
|
||||
Set proxy settings.
|
||||
rpc.get_global_prefs_override_struct(prefs, prefs_mask);
|
||||
prefs.cpu_usage_limit = 0.5;
|
||||
prefs_mask.cpu_usage_limit = true;
|
||||
rpc.set_global_prefs_override_struct(prefs, prefs_mask);
|
||||
rpc.read_global_prefs_override();
|
||||
```
|
||||
|
||||
`set_run_mode(int mode, double duration)`::
|
||||
Set the run mode (never/auto/always).
|
||||
If duration is zero, mode is permanent.
|
||||
Otherwise revert to last permanent mode after duration seconds elapse.
|
