In the C and C++ programming languages, an inline function is one qualified with the keyword inline; this serves two purposes: . It serves as a compiler directive that suggests (but does not require) that the compiler substitute the body of the function inline by performing inline expansion, i.e. by inserting the function code at the address of each function call, thereby saving the overhead ...
C++, however, requires that if a function with external linkage is declared inline in any translation unit then it must be so declared (and therefore also defined) in every translation unit where it is used, and that all the definitions of that function be identical, following the ODR. Static inline functions behave identically in C and C++.
In computing, inline expansion, or inlining, is a manual or compiler optimization that replaces a function call site with the body of the called function. Inline expansion is similar to macro expansion, but occurs during compilation, without changing the source code (the text), while macro expansion occurs prior to compilation, and results in different text that is then processed by the compiler.
Improved compatibility with several C++ features, including inline functions, single-line comments with //, mixing declarations and code, and universal character names in identifiers; Removed several dangerous C89 language features such as implicit function declarations and implicit int; Three technical corrigenda were published by ISO for C99:
A newer language construct (since C++11 and C23), constexpr allows for declaring a compile-time constant value that need not consume runtime memory. [21] Inline function. For a long time, a function-like macro was the only way to define function-like behavior that did not incur runtime function call overhead.
C++17 is a version of the ISO/IEC 14882 standard for the C++ programming language. C++17 replaced the prior version of the C++ standard, called C++14 , and was later replaced by C++20 . History
Examples include methods like Normalize(v1:vector3) and DrawDebugLine(LineStart: vector3, LineEnd: vector3). Verse supports lambda expressions and anonymous functions, allowing for inline function definitions, similar to how lambda functions are used in languages like Python or JavaScript. Verse also allows for composing functions by chaining ...
The C standard library, sometimes referred to as libc, [1] is the standard library for the C programming language, as specified in the ISO C standard. [2] Starting from the original ANSI C standard, it was developed at the same time as the C POSIX library, which is a superset of it. [3]
