sys_admin_mail_name] logdir]
DESCRIPTION

logger directory by default). When first called, creates the log file This is a daily log file, where mm indicates the month and dd indi-
cates the day of the logged messages. then appends error messages to the log file as they are received from the STREAMS log driver.
STREAMS error log messages have the following format:
seq time tick pri ind mod sub text
Components are interpreted as follows:
seq Error event sequence number.
time Time the message was sent expressed in hh:mm:ss.
tick Time the message was sent expressed in machine ticks since the last boot.
pri Error priority level as defined by the STREAMS driver or module that originates the messages.
ind Can be any combination of the following three message indicators:
The message has also been saved in the trace log.
The message signaled a fatal error.
The message has also been mailed to the system administrator.

WARNINGS
Only one process can open the STREAMS log driver at a time. This restriction is intended to maximize performance.
The STREAMS error logging mechanism works best when it is not overused. can degrade STREAMS performance by affecting the response,
throughput, and other behaviors of the drivers and modules that invoke it. also fails to capture messages if drivers and modules generate
messages at a higher rate than its optimum read rate. If there are missing sequence numbers among the messages in a log file, messages
have been lost.
