提供兩種內存分配方式：①簡單指針，②句柄（二級指針）；官方文檔建議使用前者。

// 簡單指針
char *ptr;
ptr = sysmem_newptr(2000);
post("I have a pointer %lx and it is %ld bytes in size",ptr, sysmem_ptrsize(ptr));
ptr = sysmem_resizeptrclear(ptr, 3000);
post("Now I have a pointer %lx and it is %ld bytes in size",ptr, sysmem_ptrsize(ptr));
sysmem_freeptr(ptr);// 句柄
char **hand;
hand = sysmem_newhandle(2000);
post("I have a handle %lx and it is %ld bytes in size",hand, sysmem_handlesize(hand));
sysmem_resizehandle(hand, 3000);
post("Now the handle %lx is %ld bytes in size",hand, sysmem_ptrsize(hand));
sysmem_freehandle(hand);

簡單使用示例：

typedef struct _memAlloc {t_object	ob;char* ptr;  // 定義指針
} t_memAlloc;/* ..... */void memAlloc_free(t_memAlloc* x) {sysmem_freeptr(x->ptr);  // 釋放內存
}void* memAlloc_new(t_symbol* s, long argc, t_atom* argv) {  t_memAlloc* x = (t_memAlloc*)object_alloc(memAlloc_class);x->ptr = sysmem_newptr(1024);  // 分配內存post("%lx: %ld bytes", x->ptr, sysmem_ptrsize(x->ptr));  // 打印內存地址和內存大小return (x);
}

運行結果：
