I am writing CSP code for smart card. I got a question for the flag
CRYPT_SILENT at CPAcquireContext() function. There is a description
from the document "The Smart Card Cryptographic Service Provider Cookbook".
CRYPT_SILENT: It is used to suppress any and all UI, including the PIN user
interface. The PIN must be presented programmatically for private key operations.

The description is not very clear to me.
Do I need to communicate with my smart
card when CRYPT_SILENT flag got called?

Can you give me more detail information about this flag? How will this flag affect the CSP?
