I know I can write a bind(C) function that just takes in my error message and calls error stop, and use that as a way to call error stop from a C function in a mixed fortran/C program, but is there a more direct way? I didn’t see anything about error stop in ISO\_Fortran\_binding.h so I’m assuming there is no more direct/standardized way, but I thought I would at least ask. ---

Is the main program C or Fortran? You should use the exit method suitable to the language used to create the main program. ---

The main program is Fortran in this case. I’m currently using abort() from C where needed. It works, I just feel like it would be more “elegant” to use error stop. ---

Since “error stop” is a statement and not a function/subroutine, I do not think you can do this in another way than calling a wrapper routine. (The problem is in a way similar to C macro that masquerade as functions - on the Fortran side you cannot call them directly.) ---

The safer option will be to have your Fortran main include an “error handler” procedure (say `fort_abort`) and your C side of code invoke that instead of C `abort()`. Unfortunately nothing more “elegant” than this is on tap given how primitive the `Termination of Execution" section is in the Fortran standard for application needs going back to 1990 even, let alone year 2021. ---

Check out this example, and just replace the `print` with `error stop`.

ERROR STOP is to explicitly initiate error termination with coarray programms and thus, to stop execution of a coarray app on all images as soon as possible. Advanced coarray programming, on the other hand, should rather seek to avoid error termination (by using stat= specifiers).
