CSA_LIST_ENTRY_ATTRIBUTES(3)

💅 csa_list_entry_attributes — the library call that lists the names of entry attributes 💅

okay so first things first: this is csa_list_entry_attributes, a library call (yes, section 3 energy), and it's here to spill the tea on which attributes a calendar entry has. 🫶

---

✨ NAME ✨

csa_list_entry_attributes — list the names of the entry attributes associated with the specified entry. literally just the names though, bestie, not the values, hold that thought 💖

---

🌸 SYNOPSIS 🌸

#include &<xcsa.h>
CSA_return_code csa_list_entry_attributes(
CSA_session_handle session,
CSA_entry_handle entry,
CSA_uint32 *number_names,
CSA_attribute_reference **entry_attributes_names,
CSA_extension *list_entry_attributes_extensions);

that's the whole cast of characters, no notes 👑

---

🦋 DESCRIPTION 🦋

so the csa_list_entry_attributes function lists the names of the entry attributes associated with a calendar entry. it's giving "give me the guest list, not the whole party" 💀

and here's the slay part: once you have the returned entry attributes name(s), you can go read the actual attributes value(s) using the csa_read_entry_attributes(3) function. so this is like, step one of the whole operation. main character of the pipeline, honestly ✨

---

🎀 ARGUMENTS 🎀

Session (Session Handle)

an opaque session handle that represents a session with the calendaring service. opaque means you don't peek behind the curtain, you just hold it and trust the process 💅

session handles are created by a logon function call and invalidated with a logoff function call. and ngl, if the session handle is invalid, then the error CSA_E_INVALID_SESSION_HANDLE is returned. so like, log back in, babe 😭

Entry (Entry Handle)

specifies the handle of the calendar entry that will have its attributes listed. it's the specific entry we're doing the vibe check on 🦋

if the entry handle is invalid, then the error CSA_E_INVALID_ENTRY_HANDLE is returned. rude of it, but okay, that's the rules.

List Entry Attributes Extensions (Extension)

a pointer to an array of CSA_extension structures for this function. and this array is lowkey versatile, okay, because it may contain both input extensions (for providing additional information to the function) and output extensions (for receiving information from the function) 🔥

a value of NULL indicates that the caller is not using any extensions. no extensions, no problem. see the extensions structure for more information. iykyk 📖

---

⭐ RETURN VALUE ⭐

Number Names (Uint32)

a pointer to the number of attribute names returned in entry_attribute_names. so like, the headcount of the name list 🧚

Entry Attribute Names (Attribute Reference)

a pointer to an array of attribute references containing the names of the entry attributes in the calendar entry. 💖

important bestie: this array is allocated by the service, and should be freed with a single call to csa_free(3). one call. single. don't be out here freeing it forty times 💀

List Entry Attributes 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. 🎯

💀 ERRORS 💀

the csa_list_entry_attributes function returns the following error values, and yes we're listing every single one because the details are the moment:

• CSA_E_FAILURE — there was a general failure that does not fit the description of any other error code. the "it's complicated" of error codes 🙈
• CSA_E_INSUFFICIENT_MEMORY — insufficient memory was available to complete the requested operation. the vibes were there, the RAM was not 😭
• CSA_E_INVALID_ENTRY_HANDLE — an invalid calendar entry handle was specified.
• CSA_E_INVALID_FLAG — a flag value in the flags argument was invalid.
• 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).
• CSA_E_SERVICE_UNAVAILABLE — the requested calendar service is unavailable.
• 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.
