Re: no alloca() available - alternative?

Thanx for the info. But I am out of the league with using MI. I have never used any MI function so far.

Hi, Mihael:

See:
http://www.gnu.org/s/libc/manual/html_node/Variable-Size-Automatic.html

I would not substitute "malloc" for "alloca" as that memory would never
get freed until end-of-activation-group or end-of-job.

Look in the ILE C/C++ OS/400 MI Library Reference for the modasa
function, and the MI builtin "_modasa" ... this might allow you do
create your own version of "alloca" ...

HTH,
Mark

Hi,

the ported software uses alloca() at some locations. Obviously alloca() is not support on IBM i. What is the alternative? malloc? What do I have to take into account when changing this to malloc? (besides freeing the memory afterwards)

Thanx in advance
