Dynamic library

[Ioubipgxe]

Is it feasible to call a dynamic library that uses the Tokio runtime and exposes a synchronous function interface via the C ABI from a main program that also uses the Tokio runtime?
This dynamic library internally uses tokio::runtime::Builder to create a new runtime, and the main program calls it using spawn_blocking.

It's not so easy. You must be careful to not create more than one copy of Tokio in your application. See #6927.

Thank you for your quick reply! In my case, it is not necessary for the main program and the dynamic library to use the Tokio runtime simultaneously. Is it possible to ensure safety by destroying the main program's Tokio runtime when calling functions in the dynamic library that use the Tokio runtime? If not, are there any other more reliable solutions?
