Wireshark-dev: [Wireshark-dev] Documentation error in README.dissector?

Hi,

 

README.dissector describes two accessor functions that access null terminated strings and return the string length.  The document says:

 

-----------------

gint tvb_get_nstringz(tvbuff_t *tvb, const gint offset, const guint bufsize, guint8* buffer);

gint tvb_get_nstringz0(tvbuff_t *tvb, const gint offset, const guint bufsize, guint8* buffer);

 

Returns a null-terminated buffer containing data from the specified tvbuff,

starting at the specified offset, and containing all characters from the

tvbuff up to and including a terminating null character in the tvbuff.

"*lengthp" will be set to the length of the string, including the terminating

null.

-----------------

 

I think these notes have been incorrectly copied and pasted from similar functions above this point in the doc.  Three particular points:

 

1.       We pass the address of the buffer we want to use as a parameter

2.      The value returned in the string length

3.      The length returned doesn’t include the  null terminator

 

Am I right?  Should I raise a bug?

 

Thanks and regards…Paul
