This article will explain in detail what are the predefined macros in VxWorks. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The compiler will predefine some macros, which are irrevocable. Take a look at these possible macros in VxWorks.

_ _ FILE__ string constant, which represents the current file name, including the absolute path

_ _ LINE__ decimal integer, which represents the number of the current line of code

_ _ FUNCTION__ string constant, which represents the current function name, but it is not a macro

These three are often used in debugging statements, at least in the official account VxWorks567.

_ _ TIMESTAMP__ string constant, indicating the last modification time of the current file, including 24 characters: week, month, day, hour, minute, second and year
