Microsoft Symbol Server is a Windows technology used to obtain symbol debugging information. It is built by using the SymSrv technology that is bundled with the Debugging Tools for Windows package. The SymChk.exe utility can be used to verify symbols and to build a local symbol cache in a convenient, supposedly non-invasive way.
An undefined variable in the source code of a computer program is a variable that is accessed in the code but has not been declared by that code. [1] In some programming languages, an implicit declaration is provided the first time such a variable is encountered at compile time. In other languages such a usage is considered to be sufficiently ...
Several macros affect the definitions made by windows.h and the files it includes. UNICODE – when defined, this causes the generic text datatype TCHAR to be a synonym of WCHAR instead of CHAR, and all type-generic API functions and messages that work with text will be defined to the -W versions instead of the -A versions.
DLL hell is an umbrella term for the complications that arise when one works with dynamic-link libraries (DLLs) used with older Microsoft Windows operating systems, [1] particularly legacy 16-bit editions, which all run in a single memory space.
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. Weakly defined variable symbols are marked with "V" and "v". On Solaris "nm" prints "WEAK" instead of "GLOB" for a weak symbol.
Programs call functions from Windows USER to perform operations such as creating and managing windows, receiving window messages (which are mostly user input such as mouse and keyboard events, but also notifications from the operating system), displaying text in a window, and displaying message boxes. Many of the functions in USER32.DLL call ...
Several compilers support variable-argument macros when compiling C and C++ code: the GNU Compiler Collection 3.0, [4] Clang (all versions), [8] Visual Studio 2005, [6] C++Builder 2006, and Oracle Solaris Studio (formerly Sun Studio) Forte Developer 6 update 2 (C++ version 5.3). [9] GCC also supports such macros when compiling Objective-C.
