You do not need to reference 'localhost', your C++ program and IRIS are located (and running) on the same 'localhost', the source of your problem is something else

What about the port#, I have multiple installs of Cache and one of IRIS. Does iris-callin use "1972"?

YES, directly from MGMT Portal just as you do in Cachè

In Caché you had CacheParameterFile cache.cpf with the SuperServerPort 1972
now it's named iris.cpf with DefaultPort=1972

Very interesting. So to access it before login you have to select the instance name.

But I don't see how to set the port and namespace so that IRISSECURESTARTA uses them in logging in...

I have made several callouts but never a callin (with userlogin), like you trying to do.
You wrote, you have several instances (Cache and IRIS) installed, presumably on the same hardware respective OS. Take a look in one of your Cache installation: <InstallDirectory>\dev\Cache\callin\
There are three files worth to study: sampcallin.c, sampcallint.c and shdir.c
The callin mechanism does not needs IPs and ports. To find out if anything has changed as a result of switching from Cache to IRIS, please contact WRC.

Actually its not a crash, it terminates with

Process finished with exit code -1073741515 (0xC0000135) on executing IRISSECURESTARTA.
