NAME

       gnutls_x509_trust_list_get_issuer - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int   gnutls_x509_trust_list_get_issuer(gnutls_x509_trust_list_t  list,  gnutls_x509_crt_t
       cert, gnutls_x509_crt_t * issuer, unsigned int flags);

ARGUMENTS

       gnutls_x509_trust_list_t list
                   The list

       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   unless
                   GNUTLS_TL_GET_COPY is set in  flags .

       unsigned int flags
                   flags from gnutls_trust_list_flags_t (GNUTLS_TL_GET_COPY is applicable)

DESCRIPTION

       This   function   will   find   the   issuer  of  the  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.

       Note that the flag GNUTLS_TL_GET_COPY is required for this function to  work  with  PKCS11
       trust lists in a thread-safe way.

RETURNS

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

SINCE
