与Windows OS等效的Mac OSX API

Question

I just started migrating to Mac OS X and I wanted to port a couple of tools I wrote for Windows. The question is what is the equivalent for the following:

CreateFile()
CreateFileMapping()
MapViewOfFile()

I would appreciate if someone could either guide me to a place where I can read about it or if there is some sort of a quick guide for such common questions/problems or simply answer my question.

The language of choice is C/C++ for a command line tool.

Answer 1

The equivalent of CreateFile would be open . The latter two steps for mapping a file, CreateFileMapping and MapViewOfFile , are condensed into one step on Mac OS X, with the mmap function.
