gnutls_x509_crt_get_subject_unique_id - API function
crt, char * buf, size_t *
- gnutls_x509_crt_t crt
- Holds the certificate
- char * buf
- user allocated memory buffer, will hold the unique id
- size_t * buf_size
- size of user allocated memory buffer (on input), will hold actual size of
the unique ID on return.
This function will extract the subjectUniqueID value (if present) for the given
If the user allocated memory buffer is not large enough to hold the full
subjectUniqueID, then a GNUTLS_E_SHORT_MEMORY_BUFFER error will be returned,
and buf_size will be set to the actual length.
This function had a bug prior to 3.4.8 that prevented the setting of NULL
to discover the buf_size
. To use this function safely with
the older versions the buf
must be a valid buffer that can hold at
least a single byte if buf_size
on success, otherwise a negative error code.
