NAME
gnutls_x509_crt_get_issuer_unique_id - API function
SYNOPSIS
#include <gnutls/x509.h>
int gnutls_x509_crt_get_issuer_unique_id(gnutls_x509_crt_t crt, char *
buf, size_t * buf_size);
ARGUMENTS
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.
DESCRIPTION
This function will extract the issuerUniqueID value (if present) for
the given certificate.
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 buf 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 is zero.
RETURNS
GNUTLS_E_SUCCESS on success, otherwise a negative error code.
SINCE
2.12.0
