if !exists("no_plugin_maps") && !exists("no_c_maps")

map <buffer> <silent> ,o :call FindOther("edit")<CR>

function FindOther(cmd)
let ext = expand("%:e")
let root = expand("%:t:r")
let file = ""
if ext == "c" || ext == "C" || ext == "cpp"
let target = root.".h"
let file = findfile(target)

let file = findfile(target)

if file != ""

exe a:cmd file
