gnutls_certificate_get_issuer — API function
int gnutls_certificate_get_issuer(gnutls_certificate_credentials_t sc, gnutls_x509_crt_t cert, gnutls_x509_crt_t * issuer, unsigned int flags);
- gnutls_certificate_credentials_t sc
is a gnutls_certificate_credentials_t type.
- gnutls_x509_crt_t cert
is the certificate to find issuer for
- gnutls_x509_crt_t * issuer
Will hold the issuer if any. Should be treated as constant.
- unsigned int flags
Use zero or GNUTLS_TL_GET_COPY
This function will return the issuer of a given certificate. If the flag GNUTLS_TL_GET_COPY is specified a copy of the issuer will be returned which must be freed using gnutls_x509_crt_deinit(). In that case the provided issuer must not be initialized.
As with gnutls_x509_trust_list_get_issuer() this function requires the GNUTLS_TL_GET_COPY flag in order to operate with PKCS11 trust lists in a thread-safe way.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
