gnutls_x509_crq_get_extension_by_oid2 - API function
#include <gnutls/x509.h>
int gnutls_x509_crq_get_extension_by_oid2(gnutls_x509_crq_t crq,
const char * oid, unsigned indx, gnutls_datum_t * output, unsigned
int * critical);
gnutls_x509_crq_t crq
should contain a gnutls_x509_crq_t type
const char * oid
holds an Object Identifier in a null terminated string
unsigned indx
In case multiple same OIDs exist in the extensions,
this specifies which to get. Use (0) to get the first
one.
gnutls_datum_t * output
will hold the allocated extension data
unsigned int * critical
will be non-zero if the extension is marked as
critical
This function will return the extension specified by the OID in
the certificate. The extensions will be returned as binary data
DER encoded, in the provided buffer.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative
error code in case of an error. If the certificate does not
contain the specified extension
GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
