int TVMFFIHandleDeinitOnce(void **handle_addr, int (*deinit_func)(void *handle))#

Deinitialize a handle once in a thread-safe manner.

This function checks if *handle_addr is not nullptr, and if so, calls the deinitialization function and sets *handle_addr to nullptr.

This function is thread-safe and is meant to be used by DSLs that, unlike C++, may not have static deinitialization support.

Parameters:

  • handle_addr – The address of the handle to be deinitialized.

  • deinit_func – The deinitialization function to be called if *handle_addr is not nullptr.

Returns:

0 on success, nonzero on failure.
