ifnames — Extract CPP conditionals from a set of files


ifnames [OPTION]... [FILE]...


Scan all of the C source FILES (or the standard input, if none are given) and write to the standard output a sorted list of all the identifiers that appear in those files in `#if', `#elif', `#ifdef', or `#ifndef' directives. Print each identifier on a line, followed by a space-separated list of the files in which that identifier occurs.

-h, --help
print this help, then exit
-V, --version
print version number, then exit
