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.

       unsigned int flags
                   Use zero or GNUTLS_TL_GET_COPY

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().  Note that  the
       flag  GNUTLS_TL_GET_COPY  is required for this function to work with PKCS 11 trust lists in a thread-safe
       way.

RETURNS

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