当你遇到 ValueError: mmap length is greater than file size 这个错误时,这通常是在尝试使用 Python 中的 mmap 模块对文件进行内存映射时发生的。这个错误表明你试图映射的文件区域大小超过了文件的实际大小。以下是一些可能导致此错误的原因以及如何解决它们: 原因 文件大小小于请求的大小:当你使用 mmap 的mmap.mma...

Map_length Supplied parameter. Type Integer Length Fullword (doubleword) The name of a fullword (doubleword) field that contains the size (in bytes) of the memory mapping that is to be created. The length that is specified must be less than or equal to the size of the file, and must...
Map_length parameter:When __MAP_MEGA is specified, mapping operations are performed over whole segments (megabyte chunks). If the length is not a multiple of the segment size, the entire trailing portion of the last segment will also be mapped into the user storage. ...
the length of the mapping (which must be greater than 0). 看文字mmap的功能就是为当前进程的虚拟内存分配一个新的映射,映射的起始地址是addr长度length。还可以传入一个fd,说明可以将这个虚拟地址绑定到一个文件上。 我的理解 通过看这段文字,我大概脑子里已经有一个大概的思路了。因为我花了很长的时间已经...
The region is also automatically unmapped when the process is terminated. On the other hand, closing the file descriptor does not unmap the region. The address addr must be a multiple of the page size (but length need not be). All pages containing a part of the indicated range are ...
