NAME         top

       gnutls_x509_crt_get_issuer_unique_id - API function

SYNOPSIS         top

       #include <gnutls/x509.h>

       int gnutls_x509_crt_get_issuer_unique_id(gnutls_x509_crt_t crt,
       char * buf, size_t * buf_size);

ARGUMENTS         top

       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         top

       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         top

       GNUTLS_E_SUCCESS on success, otherwise a negative error code.

SINCE         top

       2.12.0
