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 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 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 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(8) receives messages from the log driver and sends them to the standard output. strerr(8) 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(4D) 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(8) from the log driver
