Clogit(3) log server messages in local log or in system logger

SYNOPSIS

#include "Clog.h"

int Cinitlog (char *cmd, char *logfile)

int Clogit (int level, char *func, char *msg, ...)

int Cvlogit (int level, char *func, char *msg, va_list ap)

DESCRIPTION

Cinitlog initializes the server logging routines.

Clogit logs server messages in a local log or in the system logger.

Cvlogit is the same as Clogit but takes a va_list instead of a variable number of arguments.

cmd
specifies a string to be prepended to the syslog messages.
logfile
specifies a path for the server log file. If set to syslog, the system logger will be used. By default, only messages with level at least as important as LOG_INFO will be logged. The level threshold can be changed with the environment variable LOG_PRIORITY.
level
is associated with the message. The possible values, in order of decreasing importance are:
LOG_EMERG
LOG_ALERT
LOG_CRIT
LOG_ERR
LOG_WARNING
LOG_NOTICE
LOG_INFO
LOG_DEBUG
func
is the name of the function that issues the message.
msg
is a format as in printf.

RETURN VALUE

These routines return 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

ERRORS

EFAULT
logfile is a NULL pointer.
ENAMETOOLONG
The length of logfile exceeds CA_MAXPATHLEN.
