BSCLIB

The architecture of BSCLIB is centered around three primary components: the BSC Communication Manager, the API Interface, and the Data Conversion Module. The BSC Communication Manager handles the low-level details of the BSC protocol, managing connections, data transmission, and error handling. The API Interface provides a set of functions that developers use to interact with the BSC protocol.

These functions include `bsc_connect()`, `bsc_send()`, `bsc_recv()`, and `bsc_disconnect()`. The Data Conversion Module is responsible for converting data formats between the application and the mainframe, ensuring compatibility. Communication between these components is typically handled through internal function calls and data structures.

BSCLIB does not use a database or persistent storage mechanism; it focuses on real-time communication. Network requirements include connectivity to the mainframe via BSC, typically over a dedicated line or a network emulating BSC. Ports used are dependent on the specific BSC implementation and mainframe configuration.

Unlike generic communication libraries, BSCLIB is specifically designed for BSC, providing optimized performance and ease of use for this protocol. Security is managed at the network and mainframe levels, with BSCLIB providing the communication layer.
