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.
