It is true that NSS requires NSPR, but it is not true that apps that
use NSS cannot use OS-native calls for standard functions such
as I/O and memory management. Apps that use NSS can call
malloc and free for memory management and the standard I/O
functions for file I/O.
What NSS requires these apps to do is to wrap their socket I/O
in a PRFileDesc object. NSPR itself provides a default implementation
of PRFileDesc for TCP socket I/O (the PR_NewTCPSocket function),
but the apps don't have to use it. NSS implements the SSL protocol
as a PRFileDesc layer on top of the PRFileDesc layer for socket I/O.
This PRFileDesc wrapper for the socket I/O is similar to the BIO
