How can I access a file knowing only its inode?

[Rouben Rostamian]

How can I access a file (for read, write, stat, etc.) knowing only its inode
number?  I cannot find a system call or C function to do this.  Do I need to 
supply more information than just the inode?  What else is needed (short of
supplying the file name and path?)

Any hints?
