To: Charles Henry czhenry@gmail.com
I guess my real issue is that I am using an embedded piece of software
which provides its own set of memory functions, so I was just
wondering if there are any issues with mixing all these different
memory models.
Thanks,
Mike

Hi, Mike,
  There are a few Pd-specific calls, although there is no harm AFAICT
(I have used them before, but I am not an expert) with using malloc(),
calloc(), or alloca().  In m_pd.h (v. 0.40.2 for example), you will
find:
/* --------------- memory management -------------------- */
EXTERN void *getbytes(size_t nbytes);
EXTERN void *getzbytes(size_t nbytes);
EXTERN void *copybytes(void *src, size_t nbytes);
EXTERN void freebytes(void *x, size_t nbytes);
EXTERN void *resizebytes(void *x, size_t oldsize, size_t newsize);
for the pd-specific memory calls.

Hello all,
I was wondering if there are any guidelines to allocating memory in an
external? Is there any harm to using malloc/free? Or is there some
PD-specific calls that should be used?
