ne_get_error3
Error handling for http sessions
Usage
#include <ne_session.h>
const char *ne_get_error(ne_sesssion *session);
void ne_set_error(ne_sesssion *session, const char *format, ...);
Overview
The session error string is used to store any human-readable error information associated with any errors which occur whilst using the HTTP session.
The ne_get_error function returns the current session error string. This string persists only until it is changed by a subsequent operation on the session. If localisation was enabled at build time, and if necessary enabled at run-time if necessary using ne_i18n_init(3), the returned string may have been translated into the user's current locale.
The ne_set_error function can be used to set a new session error string, using a printf-style format string interface.
Return value
ne_set_error returns a constant NUL-terminated string. In the default English locale, the returned string will not have a terminating “.” period character.
Examples
Retrieve the current error string:
ne_session *sess = ne_session_create(...);
...
printf("Error was: %s\n", ne_get_error(sess));
Set a new error string:
ne_session *sess = ne_session_create(...); ... ne_set_error(sess, "Response missing header %s", "somestring");
