What you intend What the SW does Tcl Syntax
Get the value of a property. Assumes that
val
contains the
value and
var
contains a class
object.
Set val [ IGCObject_Get $var
$_ ]
Create a buffer. Makes a new buffer to fill with
packet bytes later on.
set buf [new_IGCBuffer]
Fill the buffer. This appends
the packet to the buffer
buf
.
Assumes that $pkt contains the
packet and
$buf
contains the
buffer.
IGCPacket_AppendBuffer $pkt $buf
Pop a few bits out of a buffer
into a tcl variable. Assumes that $buf contains the
buffer.
set var [IGCBuffer_Pop $buf ]
Get a few bits out of a buffer at
a certain position Assumes that $buf contains the
buffer.
set var [IGCBuffer_GetAt $buf
]
Push a few bits into a buffer. Assumes that $buf contains the
buffer.
IGCBuffer_Push $buf
Set a few bits into a buffer at a
certain position. Assumes that $buf contains the
buffer.
IGCBuffer_SetAt $buf
Print the status on the screen. NOTE: All Print() functions are
mapped into Tcl to return the
printed string. No input parameter
has to be specified!
set stat [new_IGCStatus]
IGCGenerator_UpdateStatus $gen $stat
set str [IGCStatus_Print $stat]
puts "Result: $str"
Packets ready and waiting in a buffer may not contain CRC values!
Using the functions above you can also access the buffer bitwise. The
class IGCBuffer can also be saved to file and restored from file.
NOTE
