Callback Functions
The Get access function for this subagent uses three C library functions (time, localtime,
and strftime) to determine and format the current system time:
static int
GET_systemTimeString(void *ctxt, void **indices, void *attr_ref)
{
OCTETSTRING *attr;
time_t now;
struct tm *curtime;
now = time(NULL);
curtime = localtime(&now);
systemTimeString.len = (Len_t) strftime (systemTimeString.val,
20, "%Y/%m/%d %H:%M:%S",
curtime);
attr = (OCTETSTRING *) attr_ref;
*attr = systemTimeString;
return(SNMP_ERR_NO_ERROR);
}
