It will be updated with the number of certs available. @var{file}: A file or supported URI with the certificates to load @var{format}: @code{GNUTLS_X509_FMT_DER} or @code{GNUTLS_X509_FMT_PEM} if a file is given @var{pin_fn}: a PIN callback if not globally set @var{pin_fn_userdata}: parameter for the PIN callback @var{flags}: zero or flags from @code{gnutls_certificate_import_flags} This convenience function will import a certificate chain from the given file or supported URI to @code{gnutls_pcert_st} structures. The structures must be deinitialized afterwards using @code{gnutls_pcert_deinit()} . This function will always return a sorted certificate chain. @strong{Returns:} On success, @code{GNUTLS_E_SUCCESS} (0) is returned, otherwise a negative error value; if the @code{pcert} list doesn't have enough space @code{GNUTLS_E_SHORT_MEMORY_BUFFER} will be returned. @strong{Since:} 3.6.3 @end deftypefun
