NAME         top

       gnutls_certificate_get_issuer - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       int gnutls_certificate_get_issuer(gnutls_certificate_credentials_t
       sc, gnutls_x509_crt_t cert, gnutls_x509_crt_t * issuer, unsigned
       int flags);

ARGUMENTS         top

       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

DESCRIPTION         top

       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.

RETURNS         top

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative
       error value.

SINCE         top
