Phase 6 - API Reference Expansion

Goal

Expand the API Reference section from high-level summary pages into focused per-API lookup pages.

Scope

Event Loop

Added detailed pages for:

• epoll_create1()
• epoll_ctl()
• epoll_wait()
• select()
• timerfd_create()
• timerfd_settime()

IPC

Added detailed pages for:

• ftruncate()
• munmap()
• shm_unlink()
• mq_send() / mq_receive()
• mq_close() / mq_unlink()
• sem_wait() / sem_post()
• sem_destroy()

Kernel Driver

Added detailed pages for:

• alloc_chrdev_region()
• cdev_add()
• class_create()
• copy_to_user()
• copy_from_user()
• mutex_lock() / mutex_unlock()
• spin_lock_irqsave() / spin_unlock_irqrestore()
• devm_gpiod_get()
• devm_request_threaded_irq()
• misc_register()

Result

The documentation site now behaves more like an Embedded Linux API handbook while still linking back to topic pages and labs.
