[PD-dev] Allocating memory in externals

[Charles Henry]

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.
