.SH "DESCRIPTION"
.PP
To read an HTTP response body the functions
\fBne_read_response_to_fd\fR
and
\fBne_read_response_to_buffer\fR
can be used\&. These functions are wrappers for
\fBne_read_response_block\fR
and must be called only after
\fBne_begin_request\fR
has been called successfully for the request\&.
.PP
The
\fBne_read_response_to_fd\fR
function writes the response body content to the file descriptor passed as the
\fIfd\fR
parameter\&.
.PP
The
\fBne_read_response_to_buffer\fR
function writes the response body content to the buffer passed as the
\fIbuf\fR
parameter, which has length passed via the *\fIbuflen\fR
parameter\&. On success, the *\fIbuflen\fR
is updated with the number of bytes written to the buffer\&.
.PP
After the response body has been read successfully,
\fBne_end_request\fR
must be called\&. If a failure occurs while reading the response body, the connection must be closed using
ne_close_connection\&.
.SH "RETURN VALUE"
.PP
Both functions return zero on success, or an
NE_* error code
on failure\&. The
\fBne_read_response_to_buffer\fR
function returns
NE_FAILED
if the response message length is larger than the buffer length\&.
.SH "HISTORY"
.PP
\fBne_read_response_to_buffer\fR
is available in neon 0\&.36\&.0 and later\&.
