The
sendsyslog
()
function is used to transmit a
syslog(3) formatted message
direct to syslogd(8) without
requiring the allocation of a socket. If LOG_CONS
is
specified in the flags argument, and
syslogd(8) is not accepting
messages, the message will be sent to the console. This is used internally
by syslog_r(3), so that
messages can be sent during difficult situations. If sending to
syslogd(8) fails, dropped
messages are counted. When
syslogd(8) works again, a
warning with the counter and error number is logged.
Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the error.
sendsyslog
() can fail if:
EFAULT
]EMSGSIZE
]ENOBUFS
]ENOTCONN
]The sendsyslog
() function call appeared in
OpenBSD 5.6. The flags
argument was added in OpenBSD 6.0.
