A function returns a pointer to a local variable. A function performs the assignmentglobPtr = &locVar.globPtris a global pointer variable andlocVaris a local variable. A function performs the assignment*paramPtr = &locVar.paramPtris a function parameter that is, for instance, anint**pointer...
A pointer can be null. Applying the indirection operator to a null pointer causes an implementation-defined behavior. Be aware that passing pointers between methods can cause undefined behavior. Examples are returning a pointer to a local variable through an Out or Ref parameter or as the function...
V506. Pointer to local variable 'X' is stored outside the scope of this variable. Such a pointer will become invalid. V507. Pointer to local array 'X' is stored outside the scope of this array. Such a pointer will become invalid. V508. The 'new type(n)' pattern was detected. ...

A pointer in IDL is a special variable that does not contain a “value” in the usual sense. Rather, a pointer is simply a reference to an IDL variable. The variable may be any IDL data type, including scalars, arrays, structures, and other pointers. Pointers facilitate the storage of ...

Here, type is the pointer's base type; it must be a valid C data type and var-name is the name of the pointer variable. The asterisk * used to declare a pointer is the same asterisk used for multiplication. However, in this statement the asterisk is being used to designate a variable...
If a local variable is referred to by pointers outside of its lifetime, then the behavior will be undefined and the value of the pointer becomes indeterminate. Let see the below code for a better understanding. In the below code, we try to read the value of “Data” (integer variable)...
