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. [11]
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 ...
The file to embed is specified the same as for #include – either with brackets or double quotes. The directive also allows certain parameters to be passed to it to customize its behavior. The C standard defines some parameters and implementations may define additional. The limit parameter is
BASIC, Batch files, Visual Basic:: Batch files, COMMAND.COM, cmd.exe: NB. J; from the (historically) common abbreviation Nota bene, the Latin for "note well". ⍝ APL; the mnemonic is that the glyph (jot overstruck with shoe-down) resembles a desk lamp, and hence "illuminates" the foregoing. #
Up to 4 registers are assigned to arguments in the order EAX, EDX, EBX, ECX. Arguments are assigned to registers from left to right. If any argument cannot be assigned to a register (say it is too large) it, and all subsequent arguments, are assigned to the stack. Arguments assigned to the stack are pushed from right to left.
file.s is a command-line argument which tells the program rm to remove the file named file.s. Some programming languages, such as C, C++ and Java, allow a program to interpret the command-line arguments by handling them as string parameters in the main function.
The "in" registers are used to pass arguments to the function being called, and any additional arguments need to be pushed onto the stack. However, space is always allocated by the called function to handle a potential register window overflow, local variables, and (on 32-bit SPARC) returning a struct by value.
stdarg.h is a header in the C standard library of the C programming language that allows functions to accept an indefinite number of arguments. [1] It provides facilities for stepping through a list of function arguments of unknown number and type.
