✨ NAME ✨

gnutls_x509_crq_get_attribute_info — bestie, it's an API function 💖 (it lives in the gnutls manual, section 3)

🌸 SYNOPSIS 🌸

#include <gnutls/x509.h>

int gnutls_x509_crq_get_attribute_info(gnutls_x509_crq_t crq, unsigned
                                       indx, void * oid, size_t * sizeof_oid);

🎀 ARGUMENTS 🎀

  • gnutls_x509_crq_t crq — should contain a gnutls_x509_crq_t type 🦋 like, that's the whole vibe of this one.
  • unsigned indx — Specifies which attribute number to get. Use (0) to get the first one. Zero-indexed, queen 👑
  • void * oid — a pointer to a structure to hold the OID.
  • size_t * sizeof_oid — initially holds the maximum size of oid, on return holds actual size of oid. It's giving before and after, honestly ✨

💅 DESCRIPTION 💅

Okay so this function will return the requested attribute OID in the certificate, and the critical flag for it. The attribute OID will be stored as a string in the provided buffer. Use gnutls_x509_crq_get_attribute_data() to extract the data. 🍓

If the buffer provided is not long enough to hold the output, then * sizeof_oid is updated and GNUTLS_E_SHORT_MEMORY_BUFFER will be returned. Not enough room bestie, she's telling you the size you actually need 💀

⭐ RETURNS ⭐

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code in case of an error. If your have reached the last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned. That's your cue to stop looping, no cap 🙈

🌈 SINCE 🌈

2.8.0 — an absolute veteran, been iconic since way back 🫶
