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");
