FILE descriptor <-> FILE pointers

[R. Kannan]

fdopen can be used to convert file descriptor to a FILE pointer

fileno can be used to convert a FILE pointer to file descriptor

A file descriptor is returned by open and used by dup, write, read etc

A FILE pointer is returned by fopen and used fprintf, fscanf , fget*
and printf and scanf (implicitly).


	this is in response to some netters question about
conversion from FILE pointers to file descriptors and vice versa..
