In the presence of side effects, a program's behaviour may depend on history; that is, the order of evaluation matters. Understanding and debugging a function with side effects requires knowledge about the context and its possible histories. [2] [3] Side effects play an important role in the design and analysis of programming languages. The ...
An effects loop is a series of audio effects units, connected between two points of a signal path (the route that a signal would travel from the input to the output); usually between the pre-amp and power amp stages of an amplifier circuit, although occasionally between two pre-amp stages. The two principal uses of effects loops are in ...
Requests is an HTTP client library for the Python programming language. [2] [3] Requests is one of the most downloaded Python libraries, [2] with over 300 million monthly downloads. [4] It maps the HTTP protocol onto Python's object-oriented semantics. Requests's design has inspired and been copied by HTTP client libraries for other programming ...
The request was well-formed (i.e., syntactically correct) but could not be processed. [1]: §15.5.21 423 Locked (WebDAV; RFC 4918) The resource that is being accessed is locked. [7] 424 Failed Dependency (WebDAV; RFC 4918) The request failed because it depended on another request and that request failed (e.g., a PROPPATCH). [7]
I/O completion port loops run separately from the Message loop, and do not interact with the Message loop out of the box. The "heart" of most Win32 applications is the WinMain() function, which calls GetMessage() in a loop. GetMessage() blocks until a message, or "event", is received (with function PeekMessage() as a non-blocking alternative).
Request–response pattern can be implemented synchronously ( such as web service calls over HTTP) or asynchronously. [1] In contrast, one-way computer communication, which is like the push-to-talk or "barge in" feature found on some phones and two-way radios, sends a message without waiting for a response.
A loop is a sequence of statements which is specified once but which may be carried out several times in succession. The code "inside" the loop (the body of the loop, shown below as xxx) is obeyed a specified number of times, or once for each of a collection of items, or until some condition is met, or indefinitely. When one of those items is ...
Loop unrolling, also known as loop unwinding, is a loop transformation technique that attempts to optimize a program's execution speed at the expense of its binary size, which is an approach known as space–time tradeoff. The transformation can be undertaken manually by the programmer or by an optimizing compiler.
