It's traditional to define such a thing as a real function instead of a
macro, often with the name xmalloc.
Compare with
static void*
xmalloc(JNIEnv *env, size_t size)
{
void *p = malloc(size);
if (p == NULL)
JNU_ThrowOutOfMemoryError(env, NULL);
return p;
}
#define NEW(type, n) ((type *) xmalloc(env, (n) * sizeof(type)))
