The previously written test program includes the comprehensive application of POSIX unbuffered file I/O, file addition and unlocking, process forks, and variable parameters. There is no technical content. I just want to describe it and don't want to

1) optional parametric function. For example: Because $var3 and $VAR4 are given default values in defining functions, if they are not passed to them, they are the default values, and all are optional. 2) variable parameter function

The params is used when the number of parameters is variable, that is, the number of parameters is unknown.You need to know the following points when using the params:1. If the function passes a parameter containing more than one, the parameter

Use the table pack and unpack to pack and unpack data. The test code is as follows: Print ("test table. pack () ---------------- "); function printtable (t) If type (t) =" table "thenfor K, V in pairs (t) doprinttable (v ); endelseprint (t);

The va_listva_startva_endva_arg Variable Parameter Function mainly relies on these functions to obtain parameters. These four functions are in cstdarg or stdarg. in the h package, you can use Baidu. For example, [cpp] # include #include using

We know that in Swift2, the parameter of the method is a let value by default, which is immutable.But we can add the var keyword before the parameter to change its invariance:func foo(var i:Int){ i += 1 print(i)}Unfortunately, in swift2.x+, it
