Memory-mapped files are used for accessing small segments of large files on disk, without reading the entire file into memory. NumPy's memmap's are array-like objects. This differs from Python's mmap module, which uses file-like Reading¶. Use the mmap() function to create a memory-mapped file. The first argument is a file descriptor, either from the fileno() method of a file object or from os.open().The caller is responsible for opening the file before invoking mmap(), and closing it after it is no longer needed.. The second argument to mmap() is a size in bytes for the portion of the file to map. mmap Example Willem Neal Wyndham C Programming in Linux Tutorial #067 - Memory Map using mmap() Function Everything You Always Wanted to Know About Memory in Python But Were Afraid to mmap() - Unix, Linux System Calls Manual Pages (Manpages) , Learning fundamentals of UNIX in simple and easy steps : A beginner's tutorial containing complete knowledge of Unix Korn and Bourne Shell and Programming, Utilities, File System, Directories, Memory Management, Special Variables, vi editor, Processes The mmap Module The mmap module supplies memory-mapped file objects.
