12 buf, size_t * buf_size);
13
15 gnutls_x509_crt_t crt
16 Holds the certificate
17
18 char * buf user allocated memory buffer, will hold the unique id
19
20 size_t * buf_size
21 size of user allocated memory buffer (on input), will hold
22 actual size of the unique ID on return.
23
25 This function will extract the issuerUniqueID value (if present) for
26 the given certificate.
27
28 If the user allocated memory buffer is not large enough to hold the
29 full subjectUniqueID, then a GNUTLS_E_SHORT_MEMORY_BUFFER error will be
30 returned, and buf_size will be set to the actual length.
31
32 This function had a bug prior to 3.4.8 that prevented the setting of
33 NULL buf to discover the buf_size . To use this function safely with
34 the older versions the buf must be a valid buffer that can hold at
35 least a single byte if buf_size is zero.
36
38 GNUTLS_E_SUCCESS on success, otherwise a negative error code.
