The nm command identifies weak symbols in object files, libraries, and executables. On Linux a weak function symbol is marked with "W" if a weak default definition is available, and with "w" if it is not.
WHEA "builds on the PCI Express Advanced Reporting to provide more detailed information about system errors and a common reporting structure." [ 4 ] WHEA allows third-party software to interact with the operating system and react to certain hardware events.
If the memory has been reallocated to another process, then attempting to dereference the dangling pointer can cause segmentation faults (UNIX, Linux) or general protection faults (Windows). If the program has sufficient privileges to allow it to overwrite the bookkeeping data used by the kernel's memory allocator, the corruption can cause ...
Valgrind (/ ˈ v æ l ɡ r ɪ n d /) [6] is a programming tool for memory debugging, memory leak detection, and profiling.. Valgrind was originally designed to be a freely licensed memory debugging tool for Linux on x86, but has since evolved to become a generic framework for creating dynamic analysis tools such as checkers and profilers.
Use the undefined or the null expression as a complete statement (an expression statement) when the previous methods are not allowed by the syntax. Alternatives, in situations where a function is required, are: Use the Function.prototype() built-in function, that accepts any arguments and returns undefined; [15]
HRESULT is defined in a system header file as a 32-bit, signed integer [1] and is often treated opaquely as an integer, especially in code that consumes a function that returns HRESULT.
The minimum information contained in a symbol table used by a translator and intermediate representation (IR) includes the symbol's name and its location or address. For a compiler targeting a platform with a concept of relocatability, it will also contain relocatability attributes (absolute, relocatable, etc.) and needed relocation information for relocatable symbols.
kdump (Linux) – Linux kernel's crash dump mechanism, which internally uses kexec System.map – contains mappings between symbol names and their addresses in memory, used to interpret oopses References
