🦋 DESCRIPTION 🦋

Okay, vibe check: the PROFESSION_INFOS, ADMISSION_SYNTAX, ADMISSIONS, and PROFESSION_INFO types are opaque structures representing the analogous types defined in the Common PKI Specification published by https://www.t7ev.org. You're expected to know those structures and what they mean, iykyk.

The conventional routines for converting between DER and the local format are covered in d2i_X509(3). The conventional routines for allocating and freeing the types are defined in X509_dup(3).

The PROFESSION_INFOS type is a stack of PROFESSION_INFO; see DEFINE_STACK_OF(3) for details.

The NAMING_AUTHORITY type has an authority ID and URL, and text fields. The getters return pointers to those values inside the object. The page's DESCRIPTION literally spells the URL and text ones with a double get0 — NAMING_AUTHORITY_get0_get0_authorityURL() and NAMING_AUTHORITY_get0_get0_authorityText() — alongside NAMING_AUTHORITY_get0_authorityId(). The setters free any existing value and set the pointer to the specified value, and they're written as NAMING_AUTHORITY_set0_authorityId(), NAMING_AUTHORITY_set0_get0_authorityURL(), and NAMING_AUTHORITY_set0_get0_authorityText(). Yes bestie, we keep the page's exact names, even the goofy ones. 💅

The ADMISSION_SYNTAX type has an authority name and a stack of ADMISSION objects. ADMISSION_SYNTAX_get0_admissionAuthority() and ADMISSION_SYNTAX_get0_contentsOfAdmissions() return pointers to those values within the object. ADMISSION_SYNTAX_set0_admissionAuthority() and ADMISSION_SYNTAX_set0_contentsOfAdmissions() free any existing value and set the pointer to the specified value.

The ADMISSION type has an authority name, authority object, and a stack of PROFESSION_INFO items. ADMISSIONS_get0_admissionAuthority(), ADMISSIONS_get0_namingAuthority(), and ADMISSIONS_get0_professionInfos() return pointers to those values within the object. ADMISSIONS_set0_admissionAuthority(), ADMISSIONS_set0_namingAuthority(), and ADMISSIONS_set0_professionInfos() free any existing value and set the pointer to the specified value.

The PROFESSION_INFO type has a name authority, stacks of profession Items and OIDs, a registration number, and additional profession info. PROFESSION_INFO_get0_addProfessionInfo(), PROFESSION_INFO_get0_namingAuthority(), PROFESSION_INFO_get0_professionItems(), PROFESSION_INFO_get0_professionOIDs(), and PROFESSION_INFO_get0_registrationNumber() return pointers to those values within the object. PROFESSION_INFO_set0_addProfessionInfo(), PROFESSION_INFO_set0_namingAuthority(), PROFESSION_INFO_set0_professionItems(), PROFESSION_INFO_set0_professionOIDs(), and PROFESSION_INFO_set0_registrationNumber() free any existing value and set the pointer to the specified value.

🎀 RETURN VALUES 🎀

Described above, bestie. And here's the important part:

⚠️ All of the get0 functions return a pointer to the internal data structure and must not be freed. Like, do not free them. Not even a little. 🫶
