Your code
```nim
proc download(fullpath:cstring,url:cstring) {.exportc: "download".} =
var path:string
path = splitPath($fullpath)[0]
if not existsDir(path):
echo "No such dir, but i had made it!"
createDir(path)
downloadFile2($url, $fullpath,
userAgent="Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_3_3 like Mac OS X;
en-us) AppleWebKit/533.17.9 (KHTML, like Gecko) Version/5.0.2 Mobile/8J2
Safari/6533.18.5",
)
```
means that you export c function and declare new
`download(fullpath:cstring,url:cstring)` function.
You could just export that function:
```nim
proc download(fullpath:cstring,url:cstring) {.exportc: "download".}
```
or declare it without exporting
```nim
proc download(fullpath:cstring,url:cstring) =
var path:string
path = splitPath($fullpath)[0]
if not existsDir(path):
echo "No such dir, but i had made it!"
createDir(path)
downloadFile2($url, $fullpath,
userAgent="Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_3_3 like Mac OS X;
en-us) AppleWebKit/533.17.9 (KHTML, like Gecko) Version/5.0.2 Mobile/8J2
Safari/6533.18.5",
)
```
