Synopsis

#include <gnutls/x509.h>

Description

This function will return the requested extension data in the certificate.  The extension data will be stored as a string in the provided buffer.

Use gnutls_x509_crq_get_extension_info() to extract the OID and critical flag.  Use gnutls_x509_crq_get_extension_by_oid() instead, if you want to get data indexed by the extension OID rather than sequence.

Returns

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code in case of an error.  If your have reached the last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
