I need to set the content to 0 because actually is not using malloc(), it uses
calloc() that does set the memory to 0.

It looks fine to me. I guess you don't even need to set content to 0.
I don't think malloc do it anyway. You could use bzero() instead of your for
loop.
bzero(&frame, N * 2);

Yanick & Jean-Marc,
First of all thank you very much for taking your time to try to help me.
Hi Yanick,
This is what I am trying to do, but for example the function
SpeexPreprocessState *speex_preprocess_state_init has lots of pointers that are
initialize with static inline void *speex_alloc (int size). So I am trying to
convert all this pointers into arrays but it is getting messy trying to found
out how big they need to be, and not sure if it will work. And it is not only
the struct SpeexPreprocessState_ that has lots of pointers there are other
structures with pointers too. So I am trying to replace this pointers with
arrays.
This is what I am doing but not sure if it is correct:
spx_word16_t *frame;
converted to:
spx_word16_t frame[2*N];
st-> frame = (spx_word16_t *)speex_alloc(2*N*sizeof(spx_word16_t));
converted to:
for(i=0;i<(2*N);i++)
{
st->frame[i] = 0;
}
Hi Jean-Marc
I saw the os_support.h file, but what are you suggesting to change the malloc()
with, maybe I didn't explain my self very well, my problem is that I cannot
use dynamic memory. So everything needs to be define as static with a specific
size arrays.
Again thank you both for your support.
Many thanks,
Best Regards

You don't need malloc at all. Just create a byte array like:
unsigned char buffer[160];
And use &buffer[0] as pointer in speex functions?

Dear all,
I am trying to use the Speex library pre-processor, I only need the VAD and Echo
Canceller.
I am using a STM32F103 processor, but I am using a tiny OS and it doesn't
allow to use malloc.
Is there a version of the library that will work without the need of using
malloc?
Obviously I will use all the time the same parameters, like 8kHz sampling rate,
160 frame...
I will appreciate any help or idea that you could give me.
Many thanks,
Best Regards
