Hi,
I am currently trying to make gSoap work on a PalmOs v5.2H and I have some
problems with it. In fact, I don't manage to make gSoap work with web service's
big replies.
So I was trying severals things :
First, I made a simple web service which takes a number 'n' and then reply by
sending a string of 'n' characters. When 'n' is small, there are no problems.
However, when 'n' is around 300, the Palm crashes and reset itself (without
errors). Nevertheless, there is no static limit of 'n'. It depends on a fact I
can't see.
I try so to find why gSoap crashes by learning how the PalmOS deals with
memory. gSoap uses malloc and so I ask myself what are the limits of PalmOS
memory ? What are the malloc() specifications etc... ?
Then, I can remark that malloc doesn't return NULL when it can't give memory.
So to test the allocated memory, I write in the area returned by malloc (if it
is not good, the Palm crashes :) ). I have made also a small CodeWarrior
project to test the malloc and see its limit.
Here is my story. Now my question is : why does gSoap crash ? Did i miss a
compilation option ? gSoap uses malloc : from where does malloc take the memory
? How much memory can I get with malloc ? is malloc the better solution for
large memory allocation (in knowledge database, it says to use 'MemGluePtrNew'
whereas in the dev documentation, it says to use 'malloc') ?
you can see some files on my problems on http://www.epita.fr/~guiran_a/ .
Any sort of help will be useful :)
P.S.: sorry for my bad english :S
Hi Patrick,
replace malloc with MemPtrNew() for size < 64k or MemGluePtrNew() for
all sizes. Both return NULL in case of a failure. That's for sure.
Regards
Henk
