NAME

6       gnutls_x509_crt_get_extension_data - Get the specified extension data
7

SYNOPSIS

9       #include <gnutls/x509.h>
10
11       int   gnutls_x509_crt_get_extension_data(gnutls_x509_crt_t   cert,  int
12       indx, void * data, size_t * sizeof_data);
13

ARGUMENTS

15       gnutls_x509_crt_t cert
16                   should contain a gnutls_x509_crt_t structure
17
18       int indx    Specifies which extension OID to send. Use zero to get  the
19                   first one.
20
21       void * data a pointer to a structure to hold the data (may be null)
22
23       size_t * sizeof_data
24                   initially holds the size of oid
25

DESCRIPTION

27       This  function will return the requested extension data in the certifi‐
28       cate.  The extension data will be stored as a string  in  the  provided
29       buffer.
30
31       Use  gnutls_x509_crt_get_extension_info() to extract the OID and criti‐
32       cal flag.  Use gnutls_x509_crt_get_extension_by_oid() instead,  if  you
33       want to get data indexed by the extension OID rather than sequence.
34

RETURNS

36       On  success,  GNUTLS_E_SUCCESS  (zero)  is returned, otherwise an error
37       code is returned.  If you have reached  the  last  extension  available
38       GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
