strlog(9F) Kernel Functions for Drivers strlog(9F)NAMEstrlog - submit messages to the log driver
SYNOPSIS
#include <sys/stream.h>
#include <sys/strlog.h>
#include <sys/log.h>
int strlog(short mid, short sid, char level, unsigned short flags, char
*fmt, ...););
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI).
PARAMETERS
mid Identification number of the module or driver submit‐
ting the message (in the case of a module, its mi_idnum
value from module_info(9S)).
sid Identification number for a particular minor device.
level Tracing level for selective screening of low priority
messages. Larger values imply less important informa‐
tion.
flags Valid flag values are:
SL_ERROR Message is for error logger.
SL_TRACE Message is for trace.
SL_NOTIFY Mail copy of message to system adminis‐
trator.
SL_CONSOLE Log message to console.
SL_FATAL Error is fatal.
SL_WARN Error is a warning.
SL_NOTE Error is a notice.
fmt printf(3C) style format string. %e, %g, and %G formats
are not allowed but %s is supported.
DESCRIPTION
The strlog() function expands the printf(3C) style format string passed
to it, that is, the conversion specifiers are replaced by the actual
argument values in the format string. The 32-bit representations of the
arguments (up to NLORGARGS) follow the string starting at the next
32-bit boundary following the string. Note that the 64-bit argument
will be truncated to 32-bits here but will be fully represented in the
string.
The messages can be retrieved with the getmsg(2) system call. The flags
argument specifies the type of the message and where it is to be sent.
strace(1M) receives messages from the log driver and sends them to the
standard output. strerr(1M) receives error messages from the log driver
and appends them to a file called /var/adm/streams/error.mm-dd, where
mm-dd identifies the date of the error message.
RETURN VALUES
The strlog() function returns 0 if it fails to submit the message to
the log(7D) driver and 1 otherwise.
CONTEXT
The strlog() function can be called from user, interrupt, or kernel
context.
FILES
