ne_get_error, ne_set_error - error handling for HTTP sessions

#include <ne_session.h>

const char *ne_get_error(ne_sesssion *session);

void ne_set_error(ne_sesssion *session, const char *format, ...);

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, 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.

ne_set_error returns a constant NUL-terminated string. In the default English locale, the returned string will not have a terminating “.” period character.

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");
