NAME

       upscli_readline - read a single response from a UPS

SYNOPSIS

       #include <upsclient.h>

       int upscli_readline(UPSCONN_t *ups, char *buf, size_t buflen);

DESCRIPTION

       The upscli_readline() function takes the pointer ups to a UPSCONN_t state structure,
       receives a single line from the server, and copies up to buflen bytes of the response into
       the buffer buf.

       Some parsing of the string occurs during reception. In particular, ERR messages from
       upsd(8) are detected and will cause this function to return -1.

RETURN VALUE

       The upscli_readline() function returns 0 on success, or -1 if an error occurs.
