WebA BIO is an I/O abstraction, it hides many of the underlying I/O details from an application. If an application uses a BIO for its I/O it can transparently handle SSL connections, … WebIf a BIO is appended to an SSL BIO using BIO_push () it is automatically used as the SSL BIOs read and write BIOs. Calling BIO_reset () on an SSL BIO closes down any current SSL connection by calling SSL_shutdown (). BIO_reset () is then sent to the next BIO in the chain: this will typically disconnect the underlying transport. tire shop tx
