[Samba] programming libsmbclient

[Henrik Zagerholm]

I made my own which works so far :)

Just do

m_pURLEncode = new Replace( "%", "%25" );

fd = smbc_open( m_pURLEncode->Translate(ossSMBURL.str()).c_str(),  
O_RDONLY, 0 );

So I just replace all % with %25 which is the  code for % and you  
should be ok.

Cheers,
henrik
