2009 20:01:35 +0200=0ASubject: [PATCH] The format of data we are sending =
over the network will be flexible=0A when sending over the network in =
protocol v2. To be able to do this,=0A we create a new va-list function =
that is creating the buffer to send. Also it=0A makes it easier for the =
receiver to parse the data; it sends an initial=0A header containing the =
full length of the buffer to be send. For the=0A individual strings, it =
sends sub headers containing the length of the=0A upcoming substring to be =
send. With the header-data-header-data [..]=0A structure we don't need to =
quote the sub strings finally enabling=0A having all possible character =
sets in filenames etc..=0A=0AIn the sending function, implement mkdir to =
actually send it's data=0Afor testing.=0A---=0A source3/modules/vfs_smb_tra=
