C Systems Programming

Acerca de

The C Systems Programming skill empowers Claude to architect and implement robust low-level software on Unix-like systems using standardized POSIX patterns. It provides specialized guidance for critical system-level operations including process creation via fork and exec, sophisticated signal handling for process synchronization, inter-process communication (IPC) through pipes and FIFOs, and direct system call execution. This skill is essential for developers building operating system utilities, daemons, or high-performance backend systems where direct control over system resources, file descriptors, and kernel-level interactions is required.

Características Principales

• Advanced process management using fork, execve, and waitpid patterns
• Standardized error handling patterns using errno and system-level diagnostics
• Reliable signal handling and masking for complex process lifecycles
• Synchronous inter-process communication using pipes and named FIFOs
• Robust file I/O operations with direct file descriptor and seek control
