.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"

.sp
.RS 4
.nf
ne_session *sess = ne_session_create(...);
\&...
printf("Error was: %s\en", ne_get_error(sess));
.fi
