System Programming#
Building software that interacts directly with the operating system requires understanding system calls, POSIX APIs, and the abstractions that Unix-like systems provide. System programming bridges the gap between application logic and kernel services, enabling developers to build efficient servers, daemons, and utilities.
Covered topics include file I/O operations and descriptor management, network communication through BSD sockets supporting TCP/IP and UDP protocols, signal handling for asynchronous events, and concurrent execution using threads and synchronization primitives. Mastery of these concepts is essential for developing robust network services and high-performance applications.
