Making programs against the TiCables library

# How to make a program against ticables library

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

    # include <stdio.h>
    # include <string.h>
    # include <glib.h>
    # include <ticables.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 *handle;
      int err, i;
      uint8_t buf[4];

      // init lib
      ticables_library_init();

      // set cable
      handle = ticables_handle_new(CABLE_SLV, PORT_1);
      if(handle == NULL)
          return -1;

      ticables_options_set_timeout(handle, 15);
      ticables_options_set_delay(handle, 10);
      ticables_handle_show(handle);

      // open cable
      err = ticables_cable_open(handle);
      if(err) print_lc_error(err);
      if(err) return -1;

      // do a simple test with a TI89/92+ calculator
      buf[0] = 0x08; buf[1] = 0x68; buf[2] = 0x00; buf[3] = 0x00;    // RDY
      err = ticables_cable_send(handle, buf, 4);
      if(err) print_lc_error(err);

      // display answer
      memset(buf, 0xff, 4);
      err = ticables_cable_recv(handle, buf, 4);
      if(err) print_lc_error(err);

      for(i = 0; i < 4; i++)
        printf("%02x ", buf[i]);
      printf("\n");

      // close cable
      ticables_cable_close(handle);

      // release handle
      ticables_handle_del(handle);

      // exit lib
      ticables_library_exit();

      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 -Os -g -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -Wall -W ticables.c -o ticables -lglib-2.0 -lticables2

or better

    gcc -Os -g -Wall -W `pkg-config --cflags --libs ticables2` ticables.c -o ticables
