✨ gnutls_x509_crq_get_subject_alt_name ✨

okay bestie, welcome to the gnutls manual, page gnutls_x509_crq_get_subject_alt_name(3) 💖 this one is a little API function and she is serving certificate request subject alternative names and honestly? iconic.

🌸 NAME 🌸

gnutls_x509_crq_get_subject_alt_name — API function 🎀

🦋 SYNOPSIS 🦋

#include <gnutls/x509.h>

int gnutls_x509_crq_get_subject_alt_name(gnutls_x509_crq_t crq, unsigned
int seq, void * ret, size_t * ret_size, unsigned int * ret_type,
unsigned int * critical);

💅 ARGUMENTS 💅

  • gnutls_x509_crq_t crq — should contain a gnutls_x509_crq_t type. yes bestie, that's literally what the manpage says, it's giving "the type is the type" 😭
  • unsigned int seq — the sequence number of the alt name, okay? 0 for the first one, 1 for the second etc. counting from zero like a true girlboss 🔥
  • void * ret — this is the place where the alternative name will be copied to. the drop-off spot 📦✨
  • size_t * ret_size — holds the size of ret. she's the vibe check on how much room you gave her 🫶
  • unsigned int * ret_type — holds the gnutls_x509_subject_alt_name_t name type. the what kind of name is this info 👑
  • unsigned int * critical — will be non-zero if the extension is marked as critical (may be null). so like, is this a big deal or not 💀

🎀 DESCRIPTION 🎀

This function will return the alternative names, contained in the given certificate. no cap, that's the whole gig.

It is the same as gnutls_x509_crq_get_subject_alt_name() except for the fact that it will return the type of the alternative name in ret_type even if the function fails for some reason (i.e. the buffer provided is not enough). so even when things go wrong she still tells you the type — she's not gatekeeping, periodt 💜

⭐ RETURNS ⭐

the alternative subject name type on success, one of the enumerated gnutls_x509_subject_alt_name_t. slay.

It will return GNUTLS_E_SHORT_MEMORY_BUFFER if ret_size is not large enough to hold the value. in that case ret_size will be updated with the required size. so like, she tells you exactly how much room she needs — very main character of her 💅

If the certificate request does not have an Alternative name with the specified sequence number then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned. she looked. it's not there. moving on 🙈

🌈 SINCE 🌈

2.8.0 — old money, honestly. been iconic since way back 🕰️✨
