22 @mainpage API Reference
27 The sigrok++ API provides an object-oriented C++ interface to the functionality
28 in libsigrok, including automatic memory and resource management.
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.
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.
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.
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.
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.
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.
