A void * pointer cannot be dereferenced. For example, the compiler "knows" that a pointer to int refers to four bytes of memory on a machine with four-byte integers, but a pointer to void simply contains a memory address for an unknown data typethe precise number of bytes to which the...

Pointers in dynamic languagessuch as Perl, LISP, and Java work a little differently. The run-time system sets each pointer to NULL when it is allocated and checks it each time it is dereferenced. One way to think about pointer code is that operates at two levels — pointer level and poin...
If this function is running in thread X and I remove the usb stick, and fs_unmount is invoked from another thread, then most frequently what happens is the fs_write fails and returns an error as expected, the loop breaks, fs_close is invoked and a null pointer is dereferenced. zfp->mp...
We can initialize a pointer variable when that pointer variable is not assigned any actual memory address. We can pass a null pointer to a function argument when we are not willing to pass any actual memory address. Example 1: int * aInt = NULL; ...
Here, the object r is a reference to x. It differs from a pointer to x in that it is implicitly dereferenced at all future usage; r is semantically indistinguishable from x after line 2. Furthermore, r can never be reassigned so that it refers to any variable other than x. Effectively...
There may be zero to three operands, depending on the op-code. When present, they take the form of either literals or identifiers for data items. Operand identifiers either are reserved names of registers or are assumed to be assigned to data items declared in another part of the program. ...
Consider adding the 'cin.fail()' function call to the conditional expression. V664. Pointer is dereferenced on the initialization list before its check for null inside the body of a constructor function. V665. Possible incorrect use of '#pragma warning(default: X)'. The '#pragma warning(...
Invalid pointers may not be dereferenced (since they don't point to anything). Pointers in this category include a special kind of pointer known as a null pointer, and any pointer whose memory has been freed. When a pointer is first created, it may be in either a valid or invalid state...
