slogb()

Send a message to the system logger

Synopsis:

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

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

Arguments:

opcode: A combination of a major and minor code.
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.

This function is in libc.a, but not in libc.so (in order to save space).

The slog*() functions send log messages to the system logger, slogger. 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 int's, respectively.

Errors:

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

EACCES: Insufficient permission to write to the log file.
EINVAL: The size of the data buffer exceeds 255×4 bytes, or an odd number of bytes is being read.
ENOENT: Invalid log file or directory specified, or slogger isn't running.

Examples:

See slogf().
