Minimal ObexFTP C client example

Compile with: gcc -Wall -lobexftp -o c_example c_example.c

Interesting lines are marked with /*!!!*/. The basic sequence is:

• #include <obexftp/client.h>
• obexftp_client_t *cli = NULL;
• cli = obexftp_open(OBEX_TRANS_BLUETOOTH, NULL, NULL, NULL);
• ret = obexftp_connect(cli, device, channel);
• ret = obexftp_list(cli, NULL, pathname);
• do something with cli->buf_data string
• ret = obexftp_get(cli, NULL, filename);
• do something with cli->buf_data / cli->buf_size
• ret = obexftp_disconnect(cli);

• obexftp_close(cli);

  #!c
  #include <stdio.h>
  #include <stdlib.h>

  #include <obexftp/client.h> /!!!/

  int main(int argc, char *argv[])
  {

  char *device;
  int channel;
  char *filename = NULL;
  obexftp_client_t *cli = NULL; /*!!!*/
  int ret;
  
  /* Get device, channel and optional filename */
  if (argc < 3) {
      fprintf(stderr, "Usage: %s <bt_addr> <channel> [<filename>]\n", argv[0]);
      exit(1);
  }
  device = argv[1];
         channel = atoi(argv[2]);
  if (argc > 3) {
      filename = argv[3];
  }
  
  /* Open connection */
  cli = obexftp_open(OBEX_TRANS_BLUETOOTH, NULL, NULL, NULL); /*!!!*/
  if (cli == NULL) {
      fprintf(stderr, "Error opening obexftp-client\n");
      exit(1);
  }
  
  /* Connect to client */
  ret = obexftp_connect(cli, device, channel); /*!!!*/
  if (ret < 0) {
      fprintf(stderr, "Error connecting to obexftp-client\n");
      obexftp_close(cli);
      cli = NULL;
      exit(1);
  }
  
  if (filename == NULL) {
      /* List folder */
      ret = obexftp_list(cli, NULL, "/"); /*!!!*/
      if (ret < 0) {
          fprintf(stderr, "Error getting a folder listing\n");
      } else {
          printf("%s\n", cli->buf_data); /*!!!*/
      }
  
  } else {

      ret = obexftp_get(cli, NULL, filename); /*!!!*/
      if (ret < 0) {
          fprintf(stderr, "Error getting a file\n");
      } else {
          /* do something with cli->buf_data and cli->buf_size */
      }
  }
  
  /* Disconnect */
  ret = obexftp_disconnect(cli); /*!!!*/
         if (ret < 0) {
             fprintf(stderr, "Error disconnecting the client\n");
         }
  
  /* Close */
  obexftp_close(cli); /*!!!*/
  cli = NULL;
  
  exit(0);
