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

       strlog() 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

       strlog() returns  0 if it fails to submit the message to the log(7D) driver and 1 otherwise.

CONTEXT

       strlog() can be called from user or interrupt context.

FILES

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

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