You probably want this:

FILE *myOpenFile(const char *filename) {

  FILE *File = fopen(filename, "r");
  if (File == NULL) {
      printf("Error");
      exit(0);
  }
  return File;
}

int main() {
  FILE *myFile = myOpenFile("cisfile.txt");

  // read something from myFile using fread, fgets, fscanf, etc.

  fclose(myFile);
}

I renamed some of your identifiers so the program compiles, makes sense and is less confusing.
