You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: getopt_allopts.rs
    path of file: ./repos/rustybox/libbb
    
    the code of the file until where you have to start completion: use crate::libbb::xfuncs_printf::xmalloc;
use crate::librb::size_t;
use libc;
use libc::strcpy;
extern "C" {

  #[no_mangle]
  fn strlen(__s: *const libc::c_char) -> size_t;

}
/* Specialized: */
/* Using xatoi() instead of naive atoi() is not always convenient -
 * in many places people want *non-negative* values, but store them
 * in signed int. Therefore we need this one:
 * dies if input is not in [0, INT_MAX] range. Also will
    
pub unsafe fn make_all_argv_opts(mut argv: *mut *mut libc::c_char) {
  loop
  /* Note: we skip argv[0] */
  {
    argv = argv.offset(1);
    if (*argv).is_null() {
      break;
    }
    let mut p: *mut libc::c_char = std::ptr::null_mut::<libc::c_char>();
    if *(*argv.offset(0)).offset(0) as libc::c_int == '-' as i32 {
      continue;
    }
    /* Neither top nor ps care if "" arg turns into "-" */
    /*if (argv[0][0] == '\0')
    continue;*/
    p = xmalloc(strlen(*argv).wrapping_add(2i32 as libc::c_ulong)) as *mut libc::c_char;
    *p = '-' as i32 as libc::c_char;
    strcpy(p.offset(1), *argv);
    *argv = p
