- * This file essentially replicates NSPR's source for the functions that

- * NSPR's functions, instead of duplicating them, but they're private.
- * As long as SSL's server session cache code must do platform native I/O
- * to accomplish its job, and NSPR's error mapping functions remain private,
- * this code will continue to need to be replicated.
