gnutls_x509_crt_get_extension_data - Get the specified extension data
int gnutls_x509_crt_get_extension_data(gnutls_x509_crt_t cert, int
indx, void * data, size_t * sizeof_data);
should contain a gnutls_x509_crt_t structure
int indx Specifies which extension OID to send. Use zero to get the
void * data a pointer to a structure to hold the data (may be null)
size_t * sizeof_data
initially holds the size of oid
This function will return the requested extension data in the
certificate. The extension data will be stored as a string in the
Use gnutls_x509_crt_get_extension_info() to extract the OID and
critical flag. Use gnutls_x509_crt_get_extension_by_oid() instead, if
you want to get data indexed by the extension OID rather than sequence.
On success, GNUTLS_E_SUCCESS (zero) is returned, otherwise an error
code is returned. If you have reached the last extension available
GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
