c-down-conditionalc-down-conditional is an interactive compiled Lisp function in `
cc-cmds.el'. (c-down-conditional COUNT) Move forward into the next preprocessor conditional, leaving mark behind. A prefix argument acts as a repeat count. With a negative argument, move backward into the previous preprocessor conditional. "#elif" is treated like "#else" followed by "#if", so the function stops at them when going forward, but not when going backward.
