NAME

       gnutls_certificate_get_issuer - API function

SYNOPSIS

       #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

       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

       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

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

SINCE

       3.0
