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

       3.0
