## Name

ne_get_error, ne_set_error — error handling for HTTP sessions

## Synopsis

    #include <ne_session.h>

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

## Description

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.

The `ne_set_error` function can be used to set a new session error string, using a `printf`-style format string interface.

## 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");
