UPSCLI_SENDLINE(3) ================== NAME ---- upscli_sendline, upscli_sendline_timeout - send a single command to a UPS SYNOPSIS -------- #include #include /* or 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); DESCRIPTION ----------- 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). RETURN VALUE ------------ The *upscli_sendline()* and *upscli_sendline_timeout()* functions return 0 on success, or -1 if an error occurs.
