NAME
cxLoopControlArc
- Determine whether a connection carries loop data
C SPECIFICATION
#include <cx/Info.h>
cxBoolean cxLoopControlArc( int connectID )
FORTRAN SPECIFICATION
integer function cxLoopControlArc( connectID )
integer connectID
PARAMETERS
-
connectID
-
Identifier of the output connection.
FUNCTION RETURN VALUE
Returns
cx_true
if the connection carries a loop variable.
DESCRIPTION
cxLoopControlArc
indicates whether a connection is a loop control arc. Loop control
arcs are those connections which carry loop variables -- data which
flows out of the loop controller, into the loop, out of the loop and
back into the loop controller. More specifically, control arcs
are input and output
connections of loop controllers which are connected to modules inside
the loop.
Note that the state of a connection is not valid
when the connection is first made, and it can
change because of connections or disconnections elsewhere in the map.
The only time that this call is guaranteed to be accurate is when the
user function is called because of the arrival of data.
