.SH "SYNOPSIS"
|
|

#include <upsclient\&.h>

.SH "DESCRIPTION"
|
|
.sp
|
|
The \fBupscli_readline()\fR function takes the pointer \fIups\fR to a UPSCONN_t state structure, receives a single line from the server, and copies up to \fIbuflen\fR bytes of the response into the buffer \fIbuf\fR\&.
|
|
.sp
|
|
Some parsing of the string occurs during reception\&. In particular, ERR messages from \fBupsd\fR(8) are detected and will cause this function to return \-1\&.
|
|
.SH "RETURN VALUE"
|
|
.sp
|
|
The \fBupscli_readline()\fR function returns 0 on success, or \-1 if an error occurs\&.
