SYNOPSIS

9       #include <gnutls/x509.h>
10
11       int  gnutls_x509_crq_get_extension_data(gnutls_x509_crq_t crq, unsigned
12       indx, void * data, size_t * sizeof_data);
13

ARGUMENTS

15       gnutls_x509_crq_t crq
16                   should contain a gnutls_x509_crq_t type
17
18       unsigned indx
19                   Specifies which extension number to get. Use (0) to get the
20                   first one.
21
22       void * data a pointer to a structure to hold the data (may be null)
23
24       size_t * sizeof_data
25                   initially holds the size of  oid
26

DESCRIPTION

28       This  function will return the requested extension data in the certifi‐
29       cate.  The extension data will be stored as a string  in  the  provided
30       buffer.
31
32       Use  gnutls_x509_crq_get_extension_info() to extract the OID and criti‐
33       cal flag.  Use gnutls_x509_crq_get_extension_by_oid() instead,  if  you
34       want to get data indexed by the extension OID rather than sequence.
35

RETURNS

37       On  success,  GNUTLS_E_SUCCESS  [22m(0)  is  returned, otherwise a negative
38       error code in case of an error.  If your have reached the  last  exten‐
39       sion available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
