Description:

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.
