🍓 Function Documentation 🍓

🔥 int alpm_capabilities (void ) 🔥

Get the capabilities of the library.

Returns: a bitmask of the capabilities

🍓 char * alpm_compute_md5sum (const char * filename) 🍓

Get the md5 sum of file.

Parameters:

• filename — name of the file

Returns: the checksum on success, NULL on error

🍓 char * alpm_compute_sha256sum (const char * filename) 🍓

Get the sha256 sum of file.

Parameters:

• filename — name of the file

Returns: the checksum on success, NULL on error

🦋 int alpm_sandbox_setup_child (alpm_handle_t * handle, const char * sandboxuser, const char * sandbox_path) 🦋

Drop privileges by switching to a different user.

Parameters:

• handle — the context handle
• sandboxuser — the user to switch to
• sandbox_path — if non-NULL, restrict writes to this filesystem path

Returns: 0 on success, -1 on failure

👑 alpm_pkg_t * alpm_sync_get_new_version (alpm_pkg_t * pkg, alpm_list_t * dbs_sync) 👑

Check for new version of pkg in syncdbs. If the same package appears multiple dbs only the first will be checked

This only checks the syncdb for a newer version. It does not access the network at all. See alpm_db_update to update a database.

💀 int alpm_unlock (alpm_handle_t * handle) 💀

Remove the database lock file.

Parameters:

• handle — the context handle

Returns: 0 on success, -1 on error

Note: Safe to call from inside signal handlers.

⭐ const char * alpm_version (void ) ⭐

Get the version of library.

Returns: the library version, e.g. "6.0.4"

okay bestie, we made it 🫶 — footer shoutout: source/version libalpm, page libalpm_misc(3), and the date is not printed anywhere, so we’re respectfully calling it timeless 💅✨
