// Due to a design bug of the variadic macro in C ++, the following is more readable, but should be avoided.

The declaration syntax is similar to that of variadic functions: an ellipsis "< tt >...</ tt >" is used to indicate that one or more arguments must be passed.

Without variadic macros, writing wrappers to < tt > printf </ tt > is not directly possible.

In computer programming, a variadic function is a function of indefinite arity, i. e., one which accepts a variable number of arguments.

Another operation that has been implemented as a variadic function in many languages is output formatting.

The attack is possible because the language support for variadic functions is not type-safe ; it permits the function to attempt to pop more arguments off the stack than were placed there — corrupting the stack and leading to unexpected behavior.

Note that this uses the standard lisp add function which itself is a variadic function.

This is also of use in variadic functions, such as, where the function's arguments need to be accessed as an array.

Support for variadic functions differs widely among programming languages.

To portably implement variadic functions in the C programming language, the standard < tt > stdarg. h </ tt > header file should be used.

The language's syntax borrows heavily from C. It omits or changes standard C features such as variadic functions, pointer syntax, and aspects of C's type system, because they hamper certain essential features of C -- and the ease with which code-generation tools can produce it.

In C ++, passing a non-POD data type into a variadic function such as printf will cause undefined behavior ; in GCC this means deliberately placing an illegal instruction at that point in the assembler.

To create a variadic function, an ellipsis () must be placed at the end of a parameter list.

* support for variadic macros ( macros with a variable number of arguments )

// By using the cformat string as part of the variadic arguments we can avoid this.

Fortran's variadic statement referenced a non-executable statement.

C's variadic has its origins in BCPL's function.

There are many mathematical and logical operations that come across naturally as variadic functions.

Common Lisp uses the & rest argument specifier to implement variadic functions.

Thus even if the macro "" is not defined to signify non-ANSI compliance, "" will work as shown.

Because the RDOS < tt >. systm </ tt > call macro implements a < tt > jsr </ tt >, AC3 is overwritten by the return address for the < tt >. pchar </ tt > function.

In its mathematical form it is analogous to the description of a physical wave, but its " crests " and " troughs " indicate levels of probability for the occurrence of certain phenomena ( e. g., a spark of light at a certain point on a detector screen ) that can be observed in the macro world of ordinary human experience.

A commonly applied cutoff point between " micro " and " macro " fossils is 1 mm, although this is only an approximate guide.

GW-BASIC is able to play simple music using the statement, needing a string of notes represented in a music macro language ( e. g. ).

While global macro strategies have a large amount of flexibility due to their ability to use leverage to take large positions in diverse investments in multiple markets, the timing of the implementation of the strategies is important in order to generate attractive, risk-adjusted returns.

Global macro is often categorized as a directional investment strategy.

* Focus Two: The macro perspective which focuses upon the process that innovation is diffused within a specific organization.

An even more fundamental update of the macro system was made concurrent with the development of K-Meleon 1. 1, which is based on the Gecko 1. 8. 1 rendering engine that is used in Mozilla Firefox 2. 0 and SeaMonkey 1. 1.

There is also a macro plugin which allows users to extend the browser functionality without having to know the C programming language.

A TeX macro package known as LaTeX provides a descriptive markup system on top of TeX, and is widely used.

A macrobiotic diet ( or macrobiotics ), from " macro " ( long ) and " bios, biot -" ( life ), is a dietary regimen which involves eating grains as a staple food supplemented with other foodstuffs such as local vegetables, avoiding the use of highly processed or refined foods and most animal products.

A macro ( from the Greek μακρό for " big " or " far ") in computer science is a rule or pattern that specifies how a certain input sequence ( often a sequence of characters ) should be mapped to a replacement input sequence ( also often a sequence of characters ) according to a defined procedure.

The mapping process that instantiates ( transforms ) a macro use into a specific sequence is known as macro expansion.

For this reason, use of macros is a violation of the TOS or EULA of most MMORPGs, and administrators of MMORPGs fight a continual war to identify and punish macro users.

MacroML is an experimental system that seeks to reconcile static typing and macro systems.

* m4 is a sophisticated, stand-alone, macro processor.

* The General Purpose Macroprocessor is a contextual pattern matching macro processor, which could be described as a combination of regular expressions, EBNF and AWK

The mechanism by which the code fragments are recognised ( for instance, being bracketed by < code ><? php </ code > and ) is similar to a textual macro language, but they are much more powerful, fully featured languages.

Another, less common, use of macros is to do the reverse: to map a sequence of instructions to a macro string.

The first application run in such a context is a more sophisticated and powerful macro compiler, written in the machine-independent macro language.

Lenses offered for the S2 include Summarit-S in normal ( 70 mm ), wideangle ( 35 mm ), and macro ( 120 mm ) varieties, and Tele-Elmar ( 180 mm ) portrait-length telephotos ; these are available in versions that feature integrated multi-leaf blade shutters (" Central Shutter ", or CS ), in addition to the focal-plane shutter in the camera body, to enable higher flash sync speeds.

A macro, which is also a compile-time language feature, generates code in-line using text manipulation and substitution.

Most programmers today who are aware of the term macro have encountered them in C or C ++, where they are a static feature which are built in a small subset of the language, and are capable only of string substitutions on the text of the program.

This feature allows programmers to easily write macros that span other sections of code via a " starting " and " terminating " macro pair ( along with optional " intermediate " macro invocations that are only available between the start / terminate macros ).

The HLA macro system is actually a subset of a larger feature known as the HLA Compile-Time Language ( CTL ).

Longer focal length lenses and macro lenses have a relatively long travel distance for the focusing mechanism inside the lens ; this feature shortens the autofocus time.

Tripod collar: This feature is found on most longer focal length lenses, and macro lenses.
