sia_log(3)						     Library Functions Manual							sia_log(3)

NAME
sia_log - Log events and errors - SIA (Security Integration Architecture) LIBRARY
Standard C library (libc.so and libc.a) SYNOPSIS
#include <siad.h> int sia_log( u_int loglevel, char *siafmt, ...); PARAMETERS
loglevel There are three types of log messages: SIALOGEVENT - Log an event (not an error or problem) SIALOGERROR - Log an error or problem (not too serious) SIALOGALERT - Log a serious problem (SIA is SERIOUSLY ILL) siafmt Printer format suitable for the vfprint routine. (One of the SIA message formats in sia.h.) ... The list of additional strings to be printed in the log, if any. DESCRIPTION
The sia_log() routine logs events and error messages into the sialog file. Each entry is time and PID stamped to track when and who was making the log entry. The sia_log() routine appends to an existing log file. If the log file does not exist, it is not created (no error is returned). The sia- log file is intended for debugging possible SIA problems. Use the audit subsystem for normal auditing and logging. RETURN VALUES
The sia_log() routine returns SIASUCCESS or SIAFAIL. ERRORS
The errno value is not normally set explicitly by sia_* routines. The errno values are those returned from the dynamic loader interface, from dependent (siad_*) routines, from malloc, from stdio routines such as fopen and vfprintf, or local routines such as catopen. Possible errors include resource constraints (no memory) and various authentication failures. FILES
