gnutls_x509_crt_get_extension_oid - API function
#include <gnutls/x509.h> int gnutls_x509_crt_get_extension_oid(gnutls_x509_crt_t cert, int indx, void * oid, size_t * sizeof_oid);
gnutls_x509_crt_t cert should contain a gnutls_x509_crt_t structure int indx Specifies which extension OID to send. Use zero to get the first one. void * oid a pointer to a structure to hold the OID (may be null) size_t * sizeof_oid 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.
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.
