Code example
To aid the reader in working with the mmap(2) for the purpose of file I/O, we have provided the code of a simple application; it memory maps a given file (the file's pathname, start offset, and length are provided as parameters) via the mmap(2) and hexdumps (using a, slightly enhanced, open source hexdump function) the memory region specified on to stdout. We urge the reader to look up the code, build, and try it out.
The complete source code for this book is available for cloning from GitHub here: https://github.com/PacktPublishing/Hands-on-System-Programming-with-Linux. The aforementioned program is here within the source tree: ch18/mmap_file_simple.c.
