In computing, position-independent code [1] (PIC [1]) or position-independent executable (PIE) [2] is a body of machine code that executes properly regardless of its memory address. [ a ] PIC is commonly used for shared libraries , so that the same library code can be loaded at a location in each program's address space where it does not ...
Relocation is the process of assigning load addresses for position-dependent code and data of a program and adjusting the code and data to reflect the assigned addresses. [1] [2] Prior to the advent of multiprocess systems, and still in many embedded systems, the addresses for objects are absolute starting at a known location, often zero.
To expose dangling pointer errors, one common programming technique is to set pointers to the null pointer or to an invalid address once the storage they point to has been released. When the null pointer is dereferenced (in most languages) the program will immediately terminate—there is no potential for data corruption or unpredictable behavior.
In health care, diagnosis codes are used as a tool to group and identify diseases, disorders, symptoms, poisonings, adverse effects of drugs and chemicals, injuries and other reasons for patient encounters. Diagnostic coding is the translation of written descriptions of diseases, illnesses and injuries into codes from a particular classification.
Testing for 0 such as (hr) or (!hr) will work most of the time but is incorrect for the rarely used success codes other than S_OK such as S_FALSE. To obtain the code part of an HRESULT, use the HRESULT_CODE() macro. Use the ERR.EXE tool to translate a value to the corresponding message text.

There are many cases where we know that two memory locations must be in different alias classes: Two variables of different types cannot be in the same alias class since it is a property of strongly typed, memory reference-free (i.e., references to memory locations cannot be changed directly) languages that two variables of different types ...
