13.2.6.7 Function Calls

A function is a name for a particular sequence of statements. It is defined using special definition syntax (see section 13.2.7 Function Definitions). Normally a function return some value. The way to use this value in an expression is with a function call expression, which consists of the function name followed by a comma-separated list of arguments in parentheses. The arguments are expressions which provide values for the function call environment (see section 13.2.5 Positional Parameters. When there is more than one argument, they are separated by commas. <FIXME> Actually, commas in the argument list are optional. At least, now... </> If there are no arguments, write just `()' after the function name. Here are some examples:

foo() no arguments bar(1) one argument bar(1, "string") two arguments
