Making programs against the TiCables library

# How to make a program against the ticalcs library

You will find in the test folder of the library source archive a test/example program which uses this library.
Below is a light version (most error management has been removed and update functions are set to void) of this program to make it clearer:

    #include <stdio.h>
    #include <stdlib.h>
    #include <glib.h>
    #include <ticables.h>
    #include <tifiles.h>
    #include <ticalcs.h>

    static void print_lc_error(int errnum)
    {
      char *msg;

      ticables_error_get(errnum, &msg);
      fprintf(stderr, "Link cable error (code %i)...\n<<%s>>\n", errnum, msg);

      g_free(msg);
    }

    int main(int argc, char **argv)
    {
      CableHandle* cable;
      CalcHandle* calc;
      int err;

      // init libs
      ticables_library_init();
      ticalcs_library_init();

      // set cable
      cable = ticables_handle_new(CABLE_BLK, PORT_2);
      if(cable == NULL)
        return -1;

      // set calc
      calc = ticalcs_handle_new(CALC_TI83);
      if(calc == NULL)
        return -1;

      // attach cable to calc (and open cable)
      err = ticalcs_cable_attach(calc, cable);

      err = ticalcs_calc_isready(h);
      if(err)
         print_lc_error(err);
      printf("Hand-held is %sready !\n", err ? "not " : "");

      // detach cable (made by handle_del, too)
      err = ticalcs_cable_detach(calc);

      // remove calc & cable
      ticalcs_handle_del(calc);
      ticables_handle_del(cable);

      return 0;
    }

That's all !
NOTE: for this example to work, you probably have to add compiler options related to the include path and library path, e.g.

    gcc -I/usr/include/tilp2 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -Os -g -Wall -W <...>.c -o <...> -lglib-2.0 -lticalcs2

or better

    gcc -Os -g -Wall -W `pkg-config --cflags --libs ticalcs2` ticalcs.c -o ticalcs
