For some reason, the author of the MMap module didn't see fit to
expose the "offset" parameter of the mmap syscall to python. It
would be really nice if it had that. Currently, it's always set to 0.
m_obj->data = mmap(NULL, map_size,
prot, flags,
fd, 0);

Logged In: YES user_id=341410 I agree. Having access to the offset parameter would be quite convenient, at least to some who use mmap in a nontrivial fashion. |

Logged In: YES user_id=11375 Would either of you care to provide a patch adding the parameter? I'll review it... |

Logged In: YES user_id=341410 I would, but I don't know the slightest about the C-level mmap internals on any platform, and spending the last hour looking through Python's mmap.c hasn't made me any more informed. James (or anyone else who reads this), are you able? |

Logged In: YES user_id=671362 There's already a patch for this request: http://www.python.org/sf/708374 add offset to mmap The rationale is same. It's almost ready to be committed but has been left out for a year now. So give it a second chance. |

Logged In: YES user_id=33168 The patch just needs some attention (testing and possible fixes) on Windows. |

I need map a file large than 4G in my program, But it is impossible in an 32bit system. So I need use offset parameter to map specified part of the file. I want to know when python will expose the offset parameter to us. |
