.SH "DESCRIPTION"

.PP
The session error string is used to store any human\-readable error information associated with any errors which occur whilst using the HTTP session\&.

.PP
The \fBne_get_error\fR function returns the current session error string\&. This string persists only until it is changed by a subsequent operation on the session\&.

.PP
The \fBne_set_error\fR function can be used to set a new session error string, using a \fBprintf\fR\-style format string interface\&.

.SH "EXAMPLES"

.PP
Retrieve the current error string:

.nf
ne_session *sess = ne_session_create(\&.\&.\&.);
\&.\&.\&.
printf("Error was: %s\\n", ne_get_error(sess));
.fi

.PP
Set a new error string:

.nf
ne_session *sess = ne_session_create(\&.\&.\&.);
\&.\&.\&.
ne_set_error(sess, "Response missing header %s", "somestring");
.fi
