JSCPP is an ANSI C preprocessor and language parser that can analyze and instrument C code.Currently, its most ImportAnt application is add tracing to existing C programs simply by recompiling and linking with the "JSCC" standard compiler frontend.The tracing shows when a function is entered or left with the passed parameters or return values. It is also possible to track each source line and watch read / write simple variables.Tracing is achieved by instrumenting the source code before calling the compiler system. The program is modular and can be easily extended to other types of source code modifications.What 's new in this version: · This version adds a new method of tracing, fctwrap "to generate wrappers for each function called. · This lets you see how, for example, standard library functions are called, but is less adapted to code the instrument permanently.
