nimforum mirror - How to define a proc compatible with a static C function?

Hello,

I am a newbie using Nim to call GLFW functions. I have the following function in C:


static void error_callback(int error, const char* description)
{
    fprintf(stderr, "Error: %s\n", description);
}

that I would like to implement in Nim. I have done the following:


proc error_callback(error: cint; description: cstring): void {.cdecl.} =
  quit(EXIT_FAILURE)

Need I change anything to make this compatible with the C static declaration above? Can anyone point me to where I can read up on this?

TIA

Compatible in what sense? What are you trying to do exactly?

Yes, it's compatible. Leave out the : void btw, it's unidiomatic and annoying.

@darkestpigeon1d Compatible in the sense of generating a Nim function that is the same as C the function (compiling and running).

@Araq Thank you . Will remove the void.
