NE_GET_ERROR(3)               neon API reference               NE_GET_ERROR(3)



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. 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.

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");
