gnutls_x509_crt_get_extension_data — API function
#include <gnutls/x509.h>
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
Specifies which extension OID to send. Use (0) to get the first one.
a pointer to a structure to hold the data (may be null)
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 provided buffer.
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 (0) is returned, otherwise a negative error code is returned. If you have reached the last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
