How do you dynamically allocate memory in Mac OS X assembly?
Question
I would like to dynamically allocate memory from an assembly program that does not link against the standard C library. Since brk(2) and sbrk(2) are unavailable on Mac OS X (10.6.2), what are the alternatives?
(I'm guessing that it involves a Mach call, but there seems to be little documentation around that)

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
