I came across Julia’s documentation on [printf() and stdio in the Julia runtime](https://docs.julialang.org/en/v1/devdocs/stdio/). Is there any implication on how to safely mix stdio / iostream with Julia’s IO methods, when embedding Julia in a C/C++ program? This is following up on a [problem](https://discourse.julialang.org/t/c-program-embedding-julia-works-in-terminal-but-breaks-in-pipes/86973) I have when running such a program in pipes.
