upscli_sendline - Man Page

#include <upsclient.h>
#include <time.h> /* or <sys/time.h> on some platforms */

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

int upscli_sendline_timeout(UPSCONN_t *ups, const char *buf, size_t buflen,
                               const time_t timeout);

The upscli_sendline() and upscli_sendline_timeout() functions take the pointer ups to a UPSCONN_t state structure and transmit a buffer buf of size buflen to the server.

The data in buf must be a fully formatted protocol command as no parsing of the buffer occurs within this function.

The difference between the two functions is that upscli_sendline_timeout() lets the caller decide the amount of time (timeout seconds) after which it should give up and return, whereas upscli_sendline() does not offer this freedom, and uses an immediate timeout (0 second).

The upscli_sendline() and upscli_sendline_timeout() functions return 0 on success, or -1 if an error occurs.
