[gmime-devel] Unable to parse_message

[wasiq mohammed <wasiq_md yahoo com>]

Hi There,

I am new to gmime and need your help in resolving an issue that I am facing. 
I have gmime-2.0 on my fedora. I want to parse an email and retrieve the "From", "to", "Subject" and the body 
of the message. This is my program:

static GMimeMessage *parse_message (int fd)
{
        GMimeMessage *message;
        GMimeParser *parser;
        GMimeStream *stream;

        /* create a stream to read from the file descriptor */
        stream = g_mime_stream_fs_new (fd);

        /* create a new parser object to parse the stream */
        parser = g_mime_parser_new_with_stream (stream);

        /* unref the stream (parser owns a ref, so this object does not actually get free'd until we destroy 
the parser) */
        g_object_unref (stream);

        /* parse the message from the stream */
        message = g_mime_parser_construct_message (parser);

        /* free the parser (and the stream) */
        g_object_unref (parser);

        return message;
}


int main (int argc, char **argv)
{
        GMimeMessage *message;
        InternetAddressList *addressList;
        InternetAddress *address;
        char *name;
        char *subject;
        char *from;
        char path[100];
        char command[100];
        char command1[100];
        int fd;
        int addressListLen = 0;
        int i = 0;
        if (argc < 2) {
                printf ("Usage: a.out <message file>\n");
                return 0;
        } else {
                if ((fd = open (argv[1], O_RDONLY, 0)) == -1) {
                        fprintf (stderr, "Cannot open message `%s': %s\n", argv[1], g_strerror (errno));
                        return 0;
                }
        }

        /* init the gmime library */
        g_mime_init (0);

        /* parse the message */
        message = parse_message (fd);

        if( !message )
        {
                printf("Message Parse failure\n");
                return 0;
        }
        else
        {
                printf("Message Parse Success\n");
        }
        from = g_mime_message_get_sender( message );
   
        printf("\n From \t : %s\n", from);
        printf("\n Reply To \t : %s\n", g_mime_message_get_reply_to( message));
        subject = g_mime_message_get_subject(message);

        printf("\n Subject \t : %s\n", subject);
        printf("\n message_id \t : %s\n", g_mime_message_get_message_id(message));

        addressList = g_mime_message_get_all_recipients( message );
        addressListLen = internet_address_list_length( addressList );
        printf("\n Internet Adress List Length  \t : %d\n", addressListLen);

        address = internet_address_list_get_address( addressList );
        printf("\n Reciepient Name \t : %s\n", internet_address_get_name( address ));
        printf("\n Reciepient Addr \t : %s\n", internet_address_get_addr( address ));

        return 0;
}

This program is working for some emails. But its not working for other emails. This is what is the output 
when it doesnt work:
[wasiq li656-65 gmime]$ ./test 111
Message Parse Success

 From    : (null)

 Reply To        : (null)

 Subject         : (null)

 message_id      : (null)

 Internet Adress List Length     : 0

(process:13571): gmime-CRITICAL **: internet_address_get_name: assertion `ia != NULL' failed

 Reciepient Name         : (null)

(process:13571): gmime-CRITICAL **: internet_address_get_addr: assertion `ia != NULL' failed

 Reciepient Addr         : (null)
input = (null)
str after first = (null)
str after second = (null)

 Path    : /home/wasiq/reciepts/(null)


 Appreciate any help on this - may be some sample programs or any suggestion on where I am going wrong.
