7

SYNOPSIS

9       #include <gnutls/x509.h>
10
11       int  gnutls_x509_crq_get_extension_by_oid(gnutls_x509_crq_t  crq, const
12       char * oid, int indx, void * buf, size_t *  buf_size,  unsigned  int  *
13       critical);
14

ARGUMENTS

16       gnutls_x509_crq_t crq
17                   should contain a gnutls_x509_crq_t structure
18
19       const char * oid
20                   holds an Object Identifier in a null terminated string
21
22       int indx    In  case  multiple  same OIDs exist in the extensions, this
23                   specifies which to get. Use (0) to get the first one.
24
25       void * buf  a pointer to a structure to hold the name (may be null)
26
27       size_t * buf_size
28                   initially holds the size of  buf
29
30       unsigned int * critical
31                   will be non-zero if the extension is marked as critical
32

DESCRIPTION

34       This function will return the extension specified by  the  OID  in  the
35       certificate.   The  extensions  will  be  returned  as  binary data DER
36       encoded, in the provided buffer.
37

RETURNS

39       On success, GNUTLS_E_SUCCESS (0)  is  returned,  otherwise  a  negative
40       error  code  in  case of an error.  If the certificate does not contain
41       the specified extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE  will  be
42       returned.
