Node.js programs are invoked by running the interpreter node interpreter with a given file, so the first two arguments will be node and the name of the JavaScript source file. It is often useful to extract the rest of the arguments by slicing a sub-array from process.argv .
Command-line arguments are passed in args. As in C and C++, the name "main()" is special. Java's main methods do not return a value directly, but one can be passed by using the System.exit() method. Unlike C, the name of the program is not included in args, because it is the name of the class that contains the main method, so it is already ...
getopt is a system dependent function, and its behavior depends on the implementation in the C library. Some custom implementations like gnulib are available, however. [6]The conventional (POSIX and BSD) handling is that the options end when the first non-option argument is encountered, and that getopt would return -1 to signal that.
Arguments assigned to the stack are pushed from right to left. Names are mangled by adding a suffixed underscore. Variadic functions fall back to the Watcom stack based calling convention. The Watcom C/C++ compiler also uses the #pragma aux [20] directive that allows the user to specify their own calling convention. As its manual states, "Very ...
The __VA_OPT__ macro is replaced by its argument when arguments are present, and omitted otherwise. Common compilers also permit passing zero arguments before this addition, however. [4] [6] The C preprocessor rules prevent macro names in the argument of __VA_OPT__ from expanding recursively. It is possible to work around this limitation up to ...
National economies can be run from the top down, so to speak, in what is sometimes called a command economy or they can be run from the bottom up in what is sometimes called a free market. In the ...

Writing just NULL would result in an argument of type either int or void *, neither of which is correct. Another consideration is the default argument promotions applied to the unnamed arguments. A float will automatically be promoted to a double. Likewise, arguments of types narrower than an int will be promoted to int or unsigned int. The ...
