10
11       int gnutls_x509_crq_get_extension_data(gnutls_x509_crq_t crq, int indx,
12       void * data, size_t * sizeof_data);
13

ARGUMENTS

15       gnutls_x509_crq_t crq
16                   should contain a gnutls_x509_crq_t structure
17
18       int indx    Specifies which extension number to get. Use (0) 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

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_crq_get_extension_info() to extract the OID and criti‐
32       cal flag.  Use gnutls_x509_crq_get_extension_by_oid() instead,  if  you
33       want to get data indexed by the extension OID rather than sequence.

RETURNS

36       On  success,  GNUTLS_E_SUCCESS  (0)  is  returned, otherwise a negative
37       error code in case of an error.  If your have reached the  last  exten‐
38       sion available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
