int gnutls_x509_crq_get_extension_data(gnutls_x509_crq_t cert, int indx, void * data, size_t * sizeof_data);
ARGUMENTS
gnutls_x509_crq_t cert
should contain a gnutls_x509_crq_t structure
int indx
Specifies which extension OID to send. Use zero to get the first one.
void * data
a pointer to a structure to hold the data (may be null)
size_t * sizeof_data
initially holds the size of oid
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 is returned, otherwise a
negative value in case of an error. If your have reached the
last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE
will be returned.
