    TITLE  :  Fix for signal function example




  The example for the "signal" function does not compile using
  the default compiler settings. You will receive a "cannot
  convert" message. The following is corrected version of the
  example:

  /* This example installs a signal routine to be run when
  Ctrl-Break is pressed */

  #include <stdio.h>
  #include <signal.h>
  #include <stdlib.h>

  void catcher(void) {
     printf("\nNow in break routine\n");
     exit(1);
  }

  int main(void) {
     // The original line: signal(SIGINT, catcher);
     // should be changed to the following line.

     signal(SIGFPE, (void (cdecl *)(int))catcher);

     for (;;)
        printf("\nIn main() program\n");
  }

  There are two other methods to resolve this problem. The first
  is, set the compiler for "C" Calling convention rather than
  "Standard". This is in Project|View Settings|Compiler|Code
  Generation.

  The second way would be to declare the catcher function as:

     void cdecl catcher(int x) { ... }

  Any of the above three methods will resolve the problem.
