Cadence InterProcess Communication - "hiSetBindKey freeze the Child
Process"

In my earlier post I cannot send data in my child process because I
have set a binding.

Then I tried to another solution. First I place all the data that I
will send to my child process in a skill list. Then I have unset the
binding. Then I tried to send the contents of my skill list in my
child process and I am successful.

Does hiSetBindKey freeze the Child Process?

Please comment.

No I don't think hiSetBindKey will do anything to your child process.

You should really post some code if you want relevant feedback.

Hi Step! How are you doing? I hope your doing fine.

here's my code...


procedure( ipc()
let( (childPID)
childPID = ipcBeginProcess( "command" "" 'DataHandler nil nil)
ipcWaitForProcess( childPID )
)
)

procedure( DataHandler( childPID childOutput )
evalstring( childOutput )
)


procedure( GetNames()
Bind()
)

procedure( Bind()
hiSetBindKey( "Schematics" "<Btn1down>" "BindingCmd")
)

procedure( BindingCmd()
.......
.......
if( name
AddName( name )
)
)

procedure( AddName( strName )
ipcWriteProcess(
childPID
strcat( strName "\n")
)
)


First I execute ipc(). Then in the child process I execute:

"puts -nonewline "GetNames()"
flush stdout

The evalstring will perform the "GetNames()" function.

Using the BindCmd I can select names from the schematic.

Then I must retrieve the name:

gets stdin nData

But I got an error "childPID unbound variable..." so the strName was
not transferred in my child process.

procedure( ipc()

This procedure doesn't return the child process id, and childPID is a local variable. So it's lost...

You should keep it global, to be able to access it in other procedures at any time (ie, remove the
let())
