static code analysis c#

A static 1) Background Cause: when the program executes the variable defined in the function to its definition, the compiler allocates space for it on the stack, the space allocated by the function on the stack is released at the end of the function execution. This creates a problem: If you want to save the value of this variable in the function to the next call, how to implement it? The easiest way to think of is to define a global variable, but defi

are not very different. All methods, whether static or instance, are allocated memory when the class is JIT-loaded, and the static method is referenced by the class name, and the instance method refers to the object instance. When an instance is created, no memory is allocated for the method of the class, and all instance objects share the method code of a class

Focus Static Class (Sealed+abstract) Static constructors (no arguments, unlimited characters, automatic execution once) Static variables (class-level, instance-independent, static storage) Static methods (cannot be overridden)

advantages, first, regardless of how many deposit objects are defined, the interest data members share the memory allocated in the global area, so save storage space. Second, once the interest needs to change, as soon as the change is made, the interest of all the deposit objects changes over, because they are actually sharing one thing. 　　Static member functionsFeatures: A, static member functions are

The function code is as follows: Void _ init s3c2410_map_io (struct map_desc * mach_desc, int mach_size){/* Register our io-tables */ Iotable_init (s3c2410_iodesc, array_size (s3c2410_iodesc ));Iotable_init (mach_desc, mach_size );} Next look at the structure of s3c2410_iodesc [ARCH/AR

. For example, if the developer wants to know whether printf () is defined in the hello Library mentioned above (): $ Nm libhello. so | grep printf U The printf u ing symbol printf is referenced but not defined in the function. It can be inferred that to use the hello library normally, it must be supported by other libraries, run the ldd command to check which libraries hello depends on: $ Ldd hello libc. so.6 =>/lib/libc. so.6 (0x400la000)/lib/ld-linux.so.2 =>/lib/ld-linux.so.2 (0x40000000) fro
