* This file essentially replicates NSPR's source for the functions that
|
|
* map system-specific error codes to NSPR error codes. We would use
|
|
* 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.
