22 | @mainpage API Reference | |
23 | ||
24 | Introduction | |
25 | ------------ | |
26 | ||
27 | The sigrok++ API provides an object-oriented C++ interface to the functionality | |
28 | in libsigrok, including automatic memory and resource management. | |
29 | ||
30 | It is built on top of the public libsigrok C API, and is designed to be used as | |
31 | a standalone alternative API. Programs should not mix usage of the C and C++ | |
32 | APIs; the C++ interface code needs to have full control of all C API calls for | |
33 | resources to be managed correctly. | |
34 | ||
35 | Memory management | |
36 | ----------------- | |
37 | ||
38 | All runtime objects created through the C++ API are passed and accessed via | |
39 | shared pointers, using the C++11 std::shared_ptr implementation. This means | |
40 | that a reference count is kept for each object. | |
41 | ||
42 | Shared pointers can be copied and assigned in a user's program, automatically | |
43 | updating their reference count and deleting objects when they are no longer in | |
44 | use. The C++ interface code also keeps track of internal dependencies between | |
45 | libsigrok resources, and ensures that objects are not prematurely deleted when | |
46 | their resources are in use by other objects. | |
47 | ||
48 | This means that management of sigrok++ objects and their underlying libsigrok | |
49 | resources can be treated as fully automatic. As long as all shared pointers to | |
50 | objects are deleted or reassigned when no longer in use, all underlying | |
51 | resources will be released at the right time. | |
52 | ||
53 | Getting started | |
54 | --------------- | |
55 | ||
56 | Usage of the C++ API needs to begin with a call to sigrok::Context::create(). | |
57 | This will create the global libsigrok context and returns a shared pointer to | |
58 | the sigrok::Context object. Methods on this object provide access to the | |
59 | hardware drivers, input and output formats supported by the library, as well | |
60 | as means of creating other objects such as sessions and triggers. | |
61 | ||
62 | Error handling | |
63 | -------------- | |
64 | ||
65 | When any libsigrok C API call returns an error, a sigrok::Error exception is | |
66 | raised, which provides access to the error code and description. | |
