strlog Utility
Purpose
Generates STREAMS error-logging and event-tracing messages.
Syntax
int
strlog(mid, sid, level, flags, fmt, arg1, . . . )
short mid, sid;
char level;
ushort flags;
char *fmt;
unsigned arg1;
Description
The strlog utility generates log messages within the kernel. Required definitions are contained in the sys/strlog.h file.
Parameters
mid |
Specifies the STREAMS module ID number for the module or driver submitting the log message. |
sid |
Specifies an internal sub-ID number usually used to identify a particular minor device of a driver. |
level |
Specifies a tracing level that allows for selective screening of low-priority messages from the tracer. |
flags |
Specifies the destination of the message. This can be any combination of:
SL_ERROR |
The message is for the error logger. |
SL_TRACE |
The message is for the tracer. |
SL_CONSOLE |
Log the message to the console. |
SL_FATAL |
Advisory notification of a fatal error. |
SL_WARN |
Advisory notification of a nonfatal error. |
SL_NOTE |
Advisory message. |
SL_NOTIFY |
Request that a copy of the message be mailed to the system administrator. |
|
fmt |
Specifies a print style-format string, except that %s, %f, %e, %E, %g, and %G conversion specifications are not handled. |
arg1 |
Specifies numeric or character arguments. Up to NLOGARGS (currently 4) numeric or character arguments can be provided. (The NLOGARGS variable specifies the maximum number of arguments allowed. It is defined in the sys/strlog.h file.) |
Implementation Specifics
This utility is part of STREAMS Kernel Extensions.
