gnutls_x509_crt_get_extension_oid − API function
#include <gnutls/x509.h>
int gnutls_x509_crt_get_extension_oid(gnutls_x509_crt_t cert, unsigned indx, void * oid, size_t * oid_size);
gnutls_x509_crt_t cert
should contain a gnutls_x509_crt_t type
unsigned indx
Specifies which extension OID to send. Use (0) to get the first one.
|
void * oid |
a pointer to a structure to hold the OID (may be null) |
size_t * oid_size
initially holds the size of oid
This function will return the requested extension OID in the certificate. The extension OID will be stored as a string in the provided buffer.
The oid returned will be null terminated, although oid_size will not account for the trailing null.
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.
