Can anyone tell me what function I should be using to retrieve the
error saved by ERR_add_error_data()?
After some reverse engineering, it turns out ERR_get_error_line_data()
does the trick. It was the file and line parameters that threw me off,
if you don't need them, ignore them.
This code works for me:
unsigned long e;
const char *file = NULL, *data = NULL;
int line, flags;
cfg->error = apr_psprintf(cfg->perror, "can't load CA
file %s",
nscfg->CAfile);
while ((e = ERR_get_error_line_data(&file, &line, &data,
&flags))) {
cfg->error = apr_pstrcat(cfg->perror, cfg->error, ": ",
ERR_error_string(e, NULL), NULL);
if (data) {
cfg->error = apr_pstrcat(cfg->perror, cfg->error,
": ", data, NULL);
}
}
ERR_clear_error();
Regards,
Graham
