Fastest file reading in C

Question

Right now I am using fread() to read a file, but in other language fread() is inefficient i\'v been told. Is this the same in C? If so, how would faster file reading be done

Answer 1

If you are willing to go beyond the C spec into OS specific code, memory mapping is generally considered the most efficient way.

For Posix, check out mmap and for Windows check out OpenFileMapping
