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.
