krb5_auth_con_getivector()--Get Address of the Initial Vector
Syntax
#include <krb5.h> krb5_error_code krb5_auth_con_getivector( krb5_context context, krb5_auth_context auth_context, krb5_pointer * ivec);Service Program Name: QSYS/QKRBGSS
Default Public Authority: *USE
Threadsafe: Conditional. See Usage Notes.
The krb5_auth_con_getivector() routine returns the address of the initial vector used by the specified authentication context. The application can then use this address to change the contents of the initial vector. The application, however, must not free the storage represented by the initial vector.
Authorities
No authorities are required.
Parameters
- context (Input)
- The Kerberos context.
- auth_context (Input)
- The authentication context.
- ivec (Output)
- The address of the initial vector. The authentication context still points to this vector, so any changes made to the vector may affect future data encryption operations performed using the authentication context.
Return Value
If no errors occur, the return value is 0. Otherwise, a Kerberos error code is returned.
Error Messages
Message ID | Error Message Text |
---|---|
CPE3418 E | Possible APAR condition or hardware failure. |
Usage Notes
- The Kerberos protocol runtime provides no concurrency control for the authentication context. If the application wants to use the same authentication context in multiple threads, it is the responsibility of the application to serialize access to the authentication context so that only a single thread is accessing the authentication context at any time.
