OSSL_IETF_ATTR_SYNTAX(3ossl)

💖 bestie, welcome to the OSSL_IETF_ATTR_SYNTAX(3ossl) page 💖

okay so this is the OSSL_IETF_ATTR_SYNTAX(3ossl) manual, and we are gonna get through every single detail together, no cap. It’s giving accessors-and-setters energy, but make it cute and clear ✨

🎀 NAME 🎀

OSSL_IETF_ATTR_SYNTAX, OSSL_IETF_ATTR_SYNTAX_get0_policyAuthority, OSSL_IETF_ATTR_SYNTAX_set0_policyAuthority, OSSL_IETF_ATTR_SYNTAX_get_value_num, OSSL_IETF_ATTR_SYNTAX_get0_value, OSSL_IETF_ATTR_SYNTAX_add1_value — the accessors and setters for OSSL_IETF_ATTR_SYNTAX, bestie 💅

✨ SYNOPSIS ✨

#include <openssl/x509_acert.h>

typedef struct OSSL_IETF_ATTR_SYNTAX_st OSSL_IETF_ATTR_SYNTAX;

const GENERAL_NAMES *
OSSL_IETF_ATTR_SYNTAX_get0_policyAuthority(const OSSL_IETF_ATTR_SYNTAX *a);
void OSSL_IETF_ATTR_SYNTAX_set0_policyAuthority(OSSL_IETF_ATTR_SYNTAX *a,
                                                GENERAL_NAMES *names);

int OSSL_IETF_ATTR_SYNTAX_get_value_num(const OSSL_IETF_ATTR_SYNTAX *a);
void *OSSL_IETF_ATTR_SYNTAX_get0_value(const OSSL_IETF_ATTR_SYNTAX *a,
                                       int ind, int *type);
int OSSL_IETF_ATTR_SYNTAX_add1_value(OSSL_IETF_ATTR_SYNTAX *a, int type,
                                     void *data);

🌸 DESCRIPTION 🌸

ngl, OSSL_IETF_ATTR_SYNTAX is an opaque structure that represents the IetfAttrSyntax type defined in RFC 5755 (Section 4.4) for use as an AttributeValue. iconic behavior, honestly 👑

OSSL_IETF_ATTR_SYNTAX_get0_policyAuthority() and OSSL_IETF_ATTR_SYNTAX_set0_policyAuthority() get and set the policyAuthority field of the structure. Both routines act on internal pointers of the structure and must not be freed by the application 😭 so do not go freeing those, bestie.

An OSSL_IETF_ATTR_SYNTAX object also holds a sequence of values. OSSL_IETF_ATTR_SYNTAX_get_value_num() returns the number of values in the sequence. OSSL_IETF_ATTR_SYNTAX_add1_value() adds a copy of data of a specified type to the sequence. The caller should free the data after use 🫶

OSSL_IETF_ATTR_SYNTAX_get0_value() will return the value at a specific index ind in the sequence, or NULL on error. If type is not NULL, the type of the value will be written to this location ✨

The type of the values stored in the OSSL_IETF_ATTR_SYNTAX value sequence is one of the following:

• OSSL_IETFAS_OCTETS — a pointer to an ASN1_OCTET_STRING
• OSSL_IETFAS_OID — a pointer to an ASN1_OBJECT
• OSSL_IETFAS_STRING — a pointer to an ASN1_UTF8STRING

🦋 RETURN VALUES 🦋

• OSSL_IETF_ATTR_SYNTAX_get0_policyAuthority() — returns a pointer to a GENERAL_NAMES structure, or NULL if the policy authority has not been set.
• OSSL_IETF_ATTR_SYNTAX_get_value_num() — returns the number of entries in the value sequence, or -1 on error.
• OSSL_IETF_ATTR_SYNTAX_get0_value() — returns a pointer to the value at the given index, or NULL if the index is out of range.
• OSSL_IETF_ATTR_SYNTAX_add1_value() — returns 1 on success and 0 on failure. periodt 💅

⭐ HISTORY ⭐

OSSL_IETF_ATTR_SYNTAX_get0_policyAuthority(), OSSL_IETF_ATTR_SYNTAX_set0_policyAuthority(), OSSL_IETF_ATTR_SYNTAX_get_value_num(), OSSL_IETF_ATTR_SYNTAX_get0_value(), and OSSL_IETF_ATTR_SYNTAX_add1_value() were added in OpenSSL 3.4 🔥
