SYNOPSIS

9       #include <gnutls/x509.h>
10
11       int gnutls_x509_crt_get_extension_by_oid2(gnutls_x509_crt_t cert, const
12       char * oid, int indx, gnutls_datum_t * output, unsigned  int  *  criti‐
13       cal);
14

ARGUMENTS

16       gnutls_x509_crt_t cert
17                   should contain a gnutls_x509_crt_t structure
18
19       const char * oid
20                   holds an Object Identified in null terminated string
21
22       int indx    In  case  multiple  same OIDs exist in the extensions, this
23                   specifies which to send. Use (0) to get the first one.
24
25       gnutls_datum_t * output
26                   will hold the allocated extension data
27
28       unsigned int * critical
29                   will be non-zero if the extension is marked as critical

DESCRIPTION

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

RETURNS

37       On success, GNUTLS_E_SUCCESS (0)  is  returned,  otherwise  a  negative
38       error  code is returned. If the certificate does not contain the speci‐
39       fied extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
