如何在Mac OS X程序集中动态分配内存？
[英]How do you dynamically allocate memory in Mac OS X assembly?
问题描述
I would like to dynamically allocate memory from an assembly program that does not link against the standard C library. 
我想从一个没有链接到标准C库的汇编程序动态分配内存。 Since brk(2) and sbrk(2) are unavailable on Mac OS X (10.6.2), what are the alternatives? 由于brk（2）和sbrk（2）在Mac OS X（10.6.2）上不可用，有哪些替代方案？
(I'm guessing that it involves a Mach call, but there seems to be little documentation around that) （我猜它涉及一个马赫调用，但似乎很少有文档）

可能最容易做的就是查看达尔文的资料 ，看看malloc如何在内部运作。

看起来像malloc调用mmap，它调用__mmap，看起来它只是一个系统调用
