NAME
       strlog - 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  submitting the message (in the case of a module, its mi_idnum value from mod-
		ule_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 information.

       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 administrator.

		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  repre-
       sented 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
       /var/adm/streams/error.mm-dd

	   Error messages dated mm-dd appended by strerr(1M) from the log driver
