Memory allocation problem using Call_external [message #6244]

I'm trying to run a C program using the Call_external interface.
The C program does some mallocs.

It seems IDL doesn't permit allocate memory to C program.
It's not possible to do this ?

I would greatly appreciate any help.

Thanks

IDL does not want you to allocate memory without its knowing. If you get and
read the Advanced Development Guide, it will tell you how to use the functions
IDL_MemAlloc() and IDL_MemFree() (and some others that allow IDL to do garbage
collection if you jump out in response to an error).
