    Command:

    gnutls_x509_crt_get_authority_info_access

    
    
    

    SYNOPSIS

           #include <gnutls/x509.h>
    
           int   gnutls_x509_crt_get_authority_info_access(gnutls_x509_crt_t  crt,
           unsigned int seq, int what, gnutls_datum_t * data, unsigned int * crit-
           ical);
    
    
    

    ARGUMENTS

           gnutls_x509_crt_t crt
                       Holds the certificate
    
           unsigned int seq
                       specifies  the  sequence number of the access descriptor (0
                       for the first one, 1 for the second etc.)
    
           int what    what data to get, a gnutls_info_access_what_t type.
    
           gnutls_datum_t * data
                       output data to be freed with gnutls_free().
    
           unsigned int * critical
                       pointer to output integer that  is  set  to  non-0  if  the
                       extension is marked as critical (may be NULL)
    
    
    

    DESCRIPTION

           This  function  extracts  the Authority Information Access (AIA) exten-
           sion, see RFC 5280 section  4.2.2.1  for  more  information.   The  AIA
           extension holds a sequence of AccessDescription (AD) data:
    
           <informalexample><programlisting>     AuthorityInfoAccessSyntax     ::=
           SEQUENCE SIZE (1..MAX) OF AccessDescription
    
           AccessDescription  ::=  SEQUENCE { accessMethod          OBJECT IDENTI-
           FIER,  accessLocation         GeneralName   } </programlisting></infor-
           malexample>
    
           The  seq input parameter is  used  to  indicate  which  member  of  the
           sequence  the caller is interested in.  The first member is 0, the sec-
           ond member 1 and so  on.   When  the   seq  value  is  out  of  bounds,
           GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned.
    
           The  type of data returned in  data is specified via  what which should
           be gnutls_info_access_what_t values.
    
           If  what is GNUTLS_IA_ACCESSMETHOD_OID then  data will hold the access-
           Method OID (e.g., "1.3.6.1.5.5.7.48.1").
    
           If   what is GNUTLS_IA_ACCESSLOCATION_GENERALNAME_TYPE,  data will hold
           the  accessLocation  GeneralName  type  (e.g.,  "uniformResourceIdenti-
           fier").
    
           If  what is GNUTLS_IA_URI,  data will hold the accessLocation URI data.
    
           If  data is NULL, the function does the same without storing the output
           data, that is, it will set  critical and do error checking as usual.
    
           The value of the critical flag is returned in * critical  .   Supply  a
           NULL   critical  if you want the function to make sure the extension is
           non-critical, as required by RFC 5280.
    
    
    

    RETURNS

           GNUTLS_E_SUCCESS on success, GNUTLS_E_INVALID_REQUEST on invalid  crt ,
           GNUTLS_E_CONSTRAINT_ERROR  if  the  extension  is incorrectly marked as
           critical (use a non-NULL  critical to override), GNUTLS_E_UNKNOWN_ALGO-
           RITHM   if   the  requested  OID  does  not  match  (e.g.,  when  using
           GNUTLS_IA_OCSP_URI), otherwise a negative error code.
