Functions

• __twz_rt_map_two_objects^⚠
• twz_rt_abort^⚠
  Abort immediately
• twz_rt_dealloc^⚠
  Deallocate memory. If ZERO_MEMORY is set, will clear the memory before freeing.
• twz_rt_exit^⚠
  Exit with provided code
• twz_rt_fd_close^⚠
  Close a file descriptor. If the file descriptor is invalid or already closed, this function does nothing.
• twz_rt_fd_cmd^⚠
  Perform a command on the descriptor. The arguments arg and ret are interpreted according to the command specified.
• twz_rt_fd_get_info^⚠
  Get information about a descriptor. If this returns true, the fd was valid and the data pointed to by info is filled with fd_info data.
• twz_rt_fd_open^⚠
  Open a file.
• twz_rt_fd_pread^⚠
  Read from a file. May read less than specified len.
• twz_rt_fd_preadv^⚠
  Do vectored IO read.
• twz_rt_fd_pwrite^⚠
  Write to a file. May write less than specified len.
• twz_rt_fd_pwritev^⚠
  Do vectored IO write.
• twz_rt_fd_seek^⚠
  Seek to a specified point in the file.
• twz_rt_futex_wait^⚠
  If *ptr == expected, wait until signal, optionally timing out.
• twz_rt_futex_wake^⚠
  Wake up up to max threads waiting on ptr. If max is set to FUTEX_WAKE_ALL, wake all threads.
• twz_rt_get_loaded_image^⚠
  Get a loaded image from its ID. All IDs for loaded image are sequential, starting from TWZ_RT_EXEID. On success, fill out data pointed to by the li argument and return true.
• twz_rt_get_monotonic_time^⚠
  Get time from the monotonic clock
• twz_rt_get_random^⚠
  Collect up to len bytes of randomness, filling buf. Returns the number of bytes of random data actually collected.

  Map an object with a given ID and flags.
• twz_rt_post_main_hook^⚠
• twz_rt_pre_main_hook^⚠
• twz_rt_realloc^⚠
  Reallocate memory. If ZERO_MEMORY is set, will zero new memory before returning and zero to-be-freed memory before freeing.
• twz_rt_release_handle^⚠
  Release an object handle. After calling this, the handle may not be used.
• twz_rt_runtime_entry^⚠
• twz_rt_set_name^⚠
  Set the name of the calling thread.
