(*) is used in pointer arithmetic to dereference a pointer. In other words, it is used to access the value stored at the memory address pointed to by a pointer. For example, suppose we have a pointer int *p that points to an integer variable named x. We can use the asterisk to ...
If a positional parameter is used in str(), it is interpreted as a pointer to the actual given string literal, which allows to do pointer arithmetic on it. Only addition of a single constant, less or equal to the length of the supplied string, is allowed....

Even more prone to abuse was that C used pointer arithmetic, where one could calculate any value whatsoever, use it as a memory address, and access that piece of memory no matter whether it was created by the program for this purpose or not. (Actually, these two problems are one and ...

V641. Buffer size is not a multiple of element size. V642. Function result is saved inside the 'byte' type variable. Significant bits may be lost. This may break the program's logic. V643. Suspicious pointer arithmetic. Value of 'char' type is added to a string pointer. V644. Suspi...

As you can see, it initializespfrom a global variableCTOR_ENDand subtracts 1 from it. Remember this is pointer arithmetic though and the pointer points at a function, so in this case, that -1 backs it up one function pointer, or 4 bytes. We'll see that in the assembler as well. ...
