Set HSM Context Error
If the ctx is given, and it's error value is still 0, the value will be set to 'error', and the error_message and error_action will be set to the given strings.
ctx | HSM context |
error | error code |
action | action for which the error occured |
message | error message format string |

Logout
Function that will logout the user by deleting the shared memory and semaphore. Any authenticated process will still be able to interact with the HSM.

Function that queries for a PIN, can be used as callback for hsm_open(). Stores the PIN in the shared memory.
id | Used for identifying the repository. Will have a value between zero and HSM_MAX_SESSIONS. |
repository | The repository name will be included in the prompt |
mode | The type of mode the function should run in. |
