CSA_CALL_CALLBACKS(3)

💅 csa_call_callbacks — from the csa_call_callbacks(library call) girlies ✨

okay so bestie, welcome to csa_call_callbacks(library call) — yes that's the whole manual-page name, we're being formal today 🎀

🌸 NAME 🌸

csa_call_callbacks — the function that forces the callback functions tied to whatever callback list(s) you point at to actually fire. like, no waiting around, we're invoking them on purpose, periodt 💅

---

✨ SYNOPSIS ✨

#include &<xcsa.h>
CSA_return_code csa_call_callbacks(
CSA_session_handle session,
CSA_flags reason,
CSA_extension *call_callbacks_extensions);

copy it exactly, don't be cute with the spacing, iykyk 🫶

🦋 DESCRIPTION 🦋

so here's the tea: csa_call_callbacks makes the service go call the registered callback functions that are associated with the callback list(s) you specified. the service goes through each callback list you named, and it calls the registered callback functions if there have been changes that would trigger callbacks of that type. and the order the callbacks get invoked in? implementation specific — meaning it's up to whoever built it, not you, not me, not anybody 💀

🧚 Session (Session Handle)

an opaque session handle that represents a session with the calendaring service. (opaque = you don't peek inside it, bestie, you just hold it 💜)

if you hand over a valid session handle, the callback functions registered with that session get invoked. session handles are created by a logon function call, and invalidated with a logoff function call. and if the session handle is invalid? boom, you get CSA_E_INVALID_SESSION_HANDLE back. no cap.

⭐ Reason (Flags)

this is a bitmask of flags. unspecified flags should always be passed as 0 (yes, literally always, don't test me 🙈). undocumented flags are reserved — hands off. each flag corresponds to a callback activity. the flag settings include:

• CSA_CB_CALENDAR_LOGON — if set, the new callback gets invoked when a the calendar is accessed by a user. (that "a the" is in the original and we're keeping it fr fr, we don't edit the source material 💀)
• CSA_CB_CALENDAR_DELETED — if set, the new callback gets invoked when a user requests that the calendar be deleted. bye calendar 👋
• CSA_CB_CALENDAR_ATTRIBUTE_UPDATED — if set, the new callback gets invoked whenever a calendar attribute is updated. glow-up detected 🌈
• CSA_CB_ENTRY_ADDED — if set, the new callback gets invoked whenever an entry is added to the calendar. new entry just dropped 🔥
• CSA_CB_ENTRY_DELETED — if set, the new callback gets invoked whenever an entry is deleted from the calendar. gone, reduced to atoms 💀
• CSA_CB_ENTRY_UPDATED — if set, the new callback gets invoked whenever an entry is updated on the calendar. heads up: it's implementation specific whether the callback function is invoked before or after the specified update type occurs. so don't come for me about the timing, that's not my call 🫶

🎀 Call Callbacks Extensions (Extension)

a pointer to an array of CSA_extension structures for this function. the array may contain both input extensions (for feeding extra info into the function) and output extensions (for receiving info back from the function). a value of NULL means the caller isn't using any extensions — no extensions, no problem, main character energy ✨ see the extensions structure for more information.

---

💖 RETURN VALUE 💖

🍓 Call Callbacks Extensions (Extension)

if output extensions were passed to the function in the extensions list, the results from the service will be available in the extension. see the extensions structure for more information.

and then — whether the function succeeded or not, and, if not, why. it may be success, or one of the values listed under ERRORS below. so basically: did it slay or did it flop, and if it flopped, here's the reason 😭

---

🔥 ERRORS 🔥

the csa_call_callbacks function returns the following error values:

• CSA_E_FAILURE — there was a general failure that doesn't fit the description of any other error code. the vague one. the "it's giving nothing" of errors 💀
• CSA_E_INSUFFICIENT_MEMORY — insufficient memory was available to complete the requested operation. not enough room, bestie 🥲
• CSA_E_INVALID_FLAG — a flag value in the flags argument was invalid. you passed a bad flag, it's not that deep, just fix it 🎀
• CSA_E_INVALID_FUNCTION_EXT — the function extension requested is invalid.
• CSA_E_INVALID_PARAMETER — a function parameter was invalid.
• CSA_E_INVALID_SESSION_HANDLE — the specified Session Handle is invalid or no longer valid (e.g., after logging off). you logged off, babe, that handle's expired 💅
• CSA_E_NO_AUTHORITY — the user has insufficient authority for this function. not your kingdom, not your crown 👑
• CSA_E_NOT_SUPPORTED — the operation requested is not supported by this implementation.
• CSA_E_SERVICE_UNAVAILABLE — the requested calendar service is unavailable. she's not answering the phone rn 😭
• CSA_E_UNSUPPORTED_FLAG — the flag requested is not supported.
• CSA_E_UNSUPPORTED_FUNCTION_EXT — the specified function extension is not supported or CSA_EXT_REQUIRED is set.

ngl that last one is a little sneaky — if CSA_EXT_REQUIRED is set you're getting this error even when the extension thing seems fine. read the extensions structure, bestie, it's all in there 🫶
