You are extending the stack by 17 scalars:

EXTEND(SP,17);</c>
<p>But then pushing a single scalar <c>PUSHs( sv_2mortal( ...) );</c> 

<p>And that scalar is an SvPV that points to a C-string: <c>newSVpv( (
+char*)array,(int)len )</c>

<p>If you want to push that string as 16 (no point in return the null 
+in a searate scalar) individual unisgned values, you will need to loo
+p over the string extracting the byte values, creating SvUV's from ea
+ch one and then push each onto the stack. 

<p>Something like:<code>
EXTEND( SP, 16 );
for( i=0; i < 16; ++i ) 
    PUSHs( sv_2mortal( newSVuv( array[ i ] ) ) );

Also, there is no point in this: sv_setpvn(session_id, "\0",len); //Intializing it to NULL? Don't know if this wrks

1) it will already have been initialised to nulls by newSVpvn(array,17); //allocating memory 16 + 1 for null

2) if it wasn't initialised to nulls it wouldn't matter because the Xsession() sub is going to overwrite it anyway.

The start of some sanity?
