slogb()

Send a message to the system logger

Synopsis:

#include <stdio.h>
#include <sys/slog.h>

int slogb( int opcode, 
           int severity, 
           void * data, 
           int size );

Arguments:

opcode: A combination of a major and minor code. Create the opcode using the _SLOG_SETCODE(major, minor) macro that's defined in <sys/slog.h>.
Use major codes in the range _SLOGC_PRIVATE_START and _SLOGC_PRIVATE_END in your applications, keeping in mind that many applications already use _SLOGC_TEST, which is (_SLOGC_PRIVATE_START + 0).
severity: The severity of the log message; see “Severity levels,” in the documentation for slogf().
data: A block of raw data.
size: The size of the raw data.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The slog*() functions send log messages to the system logger, slogger2. To send formatted messages, use slogf(). If you have programs that scan log files for specified codes, you can use slogb() or slogi() to send a block of structures or ints, respectively.

Errors:

Any value from the Errors section in MsgSend(), as well as:

EACCES: Insufficient permission to write to the log file.
ENOENT: Invalid log file or directory specified, or slogger2 isn't running.

Examples:

See slogf().
