application binary interface
An interface application binary interface is an interface between two independently compiled modules of a program. An Application Binary Interface document specifies a set of conventions such as the order and location of function arguments that compilers must adhere to in order to achieve interoperability between such modules.

basic exception safety [Stroustrup 01], [ Sutter 00]
The basic exception safety guarantee is a property of an operation such that, if the operation terminates by raising an exception, it preserves program state invariants and prevents resource leaks. (See also exception safety, and strong exception safety, and no-throw guarantee.)

data race data race

data race [ISO/IEC 14882-2014]
The execution of a program contains a data race if it contains two potentially concurrent conflicting actions, at least one of which is not atomic, and neither happens before the other, except . [An exception is]that two accesses to the same object of type volatile sig_atomic_t do not result in a data race if both occur in the same thread, even if one or more occurs in a signal handler.

diagnostic message diagnostic message

diagnostic message [ISO/IEC 14882-2014]
A diagnostic message is a message belonging to an implementation-defined subset of the implementation’s message output. A diagnostic message may indicate a constraint violation or a valid, but questionable, language construct. Messages typically include the file name and line number pointing to the offending code construct. In addition, implementations also often indicate the severity of the problem. Although the C++ Standard does not specify any such requirement, the most severe problems often cause implementations to fail to fully translate a translation unit. Diagnostics output in such cases are termed errors. Other problems may cause implementations simply to issue a warning message and continue translating the rest of the program. (See error message and warning message.)

RAII RAII

RAII (Resource Acquisition Is Initialization)
An acronym that stands for: Resource Acquisition Is InitializationRAII is a design principle supported by C++. Holding a resource is a class invariant where the allocation of the resource (acquisition) is inseparable from the initialization of the object during its construction. Further, deallocation of the resource is performed during the destruction of the object. Thus, the resource is held when initialization completes and remains held until finalization begins, ensuring there are no resource leaks unless the object owning the resource is also leaked.

valid pointer valid pointer

valid pointer
A valid pointer is a pointer that refers to an element within an array or one past the last element of an array. For the purposes of this definition, a pointer to an object that is not an element of an array behaves the same as a pointer to the first element of an array of length one with the type of the object as its element type. For the purposes of this definition, an object can be considered to be an array of a certain number of bytes; that number is the size of the object, as produced by the sizeof operator.
