coin_threads(3)

✨ NAME ✨

okay so bestie, lemme introduce you to coin_threads — aka the Portable Threads Abstraction Classes from Coin. yes it's section 3 of the Coin manual, yes it's giving very much "i contain multitudes", and yes you're gonna want to read this whole thing because there's a LOT of little type definitions in here and they all matter. 💅

🦋 SYNOPSIS 🦋

🎀 Typedefs 🎀

these are the lil type definitions, the building blocks, the main characters of this whole file. one bullet each, no skipping, i promise:

• typedef struct cc_thread cc_thread — the type definition for the thread structure. yes bestie, that's literally what a thread is in here.
• typedef struct cc_mutex cc_mutex — the type definition for the mutex structure. the classic "one at a time please" energy.
• typedef struct cc_rwmutex cc_rwmutex — the type definition for the read-write mutex structure.
• typedef struct cc_storage cc_storage — the type definition for the thread local memory storage structure. ur own private lil stash, per-thread. 🫶
• typedef struct cc_condvar cc_condvar — the type definition for the conditional variable structure.
• typedef struct cc_worker cc_worker — the type definition for the worker thread structure. clocking in, doing the job, iconic. 👑
• typedef struct cc_wpool cc_wpool — the type definition for a worker pool structure. it's a whole squad of workers.
• typedef struct cc_recmutex cc_recmutex — the type definition for the recursive mutex structure.
• typedef struct cc_sched cc_sched — the type definition for the thread scheduler structure. she decides who goes when.
• typedef struct cc_fifo cc_fifo — the type definition for the first-in, first-out queue structure. no cutting the line, periodt.
• typedef struct cc_barrier cc_barrier — the type definition for the thread barrier structure. everyone waits at the rope until the whole group is ready. 🌈

🌸 Enumerations 🌸

and now the enums, which are also essential, also not skippable:

• enum cc_threads_implementation { CC_NO_THREADS = -1, CC_PTHREAD = 0, CC_W32THREAD } — the type definition for the implemented thread enumerator. literally which threading flavour u got: CC_NO_THREADS (value -1), CC_PTHREAD (value 0), or CC_W32THREAD.
• enum cc_retval { CC_ERROR = 0, CC_OK = 1, CC_TIMEOUT, CC_BUSY } — the type definition for the return value enumerator. so like, CC_ERROR is 0, CC_OK is 1, then CC_TIMEOUT and CC_BUSY are just vibing there after them. ngl these are the ones you'll be checking fr fr.
• enum cc_precedence { CC_READ_PRECEDENCE, CC_WRITE_PRECEDENCE } — the type definition of the cc_precedence enumerator. which side gets priority, reads or writes, ur call bestie.

💖 Detailed Description 💖

so the whole point, the thesis statement, the moment: Coin implements a set of abstractions over the native threads data types that can be portably used across all the platforms Coin has been ported to.

that's it. that's the tea. 🍓 you write against these lil cc_ types, and Coin handles the whole "but what if the platform is different" situation for you. no cap, that's the entire flex. write once, run wherever Coin went. ✨
