ucpp

A preprocessor compliant to C99

ucpp is a preprocessor for C source code, specifically code compliant to the ISO standard 9899:1999, also known as C99. A preprocessor is responsible for macro replacement, conditional compilation and inclusion of header files. ucpp operates in two modes: -- lexer mode: ucpp is linked to some other code and outputs a stream of tokens (each call to the lex() function will yield one token) -- non-lexer mode: ucpp preprocesses text and outputs the resulting text to a file descriptor; if linked to some other code, the cpp() function must be called repeatedly, otherwise ucpp is a stand-alone binary.
