Hi ,
I wanted to print a message in the decode_gtp_cause function. But i did not get any such result in the ethereal display. Please tell me what may be the reason.
the following is the function :
static int decode_gtp_cause(tvbuff_t *tvb, int offset, packet_info *pinfo _U_, p
roto_tree *tree) {
guint8 cause;
guint16 length; /* added by me */
length = 222;
cause = tvb_get_guint8(tvb, offset+1);
printf("How are you\n"); /*added by me */
proto_tree_add_uint(tree, hf_gtp_cause, tvb, offset, 2, cause);
proto_tree_add_text(tree, tvb, offset+3, 2, "Length : %u", length); /*added by
me */
return 2;
}
The corresponding part of ethereal display is as follows :
Cause : Request accepted (128)
Length : 222
I wanted my message "Length = 222" to occur along with the above output.
But as it is clear here it did not appear.
Please any body tell me the reason.
Regards,
