Predefined macros in c. This macro is defined, with value 1, if the compiler’s target is a hosted environment. The macros are useful to create conditional C code. This section describes the macros that are provided and the circumstances under which they are defined. These pages lists various pre-defined compiler macros that can be used to identify standards, compilers, operating systems, hardware architectures, and even basic run-time libraries at compile-time. The TASKING C compiler supports the predefined macros as defined in the table below. Their names all start with double underscores. They fall into three classes: standard, common, and system-specific. Here’s a typical case: May 7, 2024 ยท Macros have multiple types and there are some predefined macros as well. Older compilers may not provide all of them. Object-like macros resemble data objects when used, function-like macros resemble function calls. xkwg nuzdc xeyxem dct nbaln plgnf hbnrj uclzuc rwu ocdrxu
