Citeren Robert Jobbagy <[email protected]>:
This is my shutdown function:
void upsdrv_shutdown(void)
{
int ret;
fprintf(stderr,"SHUTDOWN 1");
This doesn't work. The driver backgrounds before it reaches this
point, so you can't use fprintf at this point anymore.
ret = ser_send_buf(upsfd, cmd_UPSShutdown0, SHUTDOWN_CMD_LEN);
if (ret < 0) {
upsdebug_with_errno(2, "send");
return -1;
}
else if (ret < 6) {
upsdebug_hex(2, "send: truncated", cmd_UPSShutdown0, ret);
return -1;
}
A void function can't return a value. Does the above actually compile
without errors? If it does, change the compiler flags so that it
doesn't. Also make sure that you're running your freshly compiled
driver.
[...]
These commands works other way , but in this function didnt work
And I cant found the "SHUTDOWN 1,2,3" test texts in debug.log, so I think
dont sent these commands to UPS.
See above.
Best regards, Arjen
