Module Log

module Log: sig  end

The definitions for the event logger. It is used to log debugging, error and informational messages. It should only be used through the LOG keyword introduced by the logifier.pl preprocessor.

type severity =

`\|`	`Emerg`	`(*`	`This event needs a human intervention to recover. The entire system is compromised and execution is aborted.`	`*)`
`\|`	`Alert`	`(*`	`Something went wrong and at least one thread of execution was not recovered.`	`*)`
`\|`	`Error`	`(*`	`Recovered error. Needs investigation.`	`*)`
`\|`	`Warning`	`(*`	`Something is fishy. Needs investigation.`	`*)`
`\|`	`Exceptional`	`(*`	`A secondary code flow.`	`*)`
`\|`	`Config`	`(*`	`Configuration setup of change.`	`*)`
`\|`	`User`	`(*`	`Used-invoked alteration.`	`*)`
`\|`	`Info`	`(*`	`Informational message. Something significant has happened.`	`*)`
`\|`	`Exec`	`(*`	`Tracing the execution flow.`	`*)`
`\|`	`Debug`	`(*`	`Debugging information.`	`*)`
`\|`	`Data`	`(*`	`Parameter dumps.`	`*)`

The severity of a log event.

val protect : Mutex.t

Do not use - it is referenced only through the logifier.pl preprocessing script.

val event : severity ->
       int -> string -> ('a, Pervasives.out_channel, unit) format -> 'a

Do not use. Log.event sev count modu msg will log message msg with severity sev, with a reference to module modu and line number count. . See the module introduction.

val cur_log_level : severity Pervasives.ref

Used to set the current logging level. Can be changed at any time.

val log_out : Pervasives.out_channel

The channel where we print the log messages. Do not use - it is referenced only through the logifier.pl script.

val log_from_string : string -> unit

Set the cur_log_level according to the string passed as parameter, which should be a representation of the log levels defined above. Raises a Failure if the parameter is not a valid string representation of a log level.

val cmp : severity -> bool

Do not use. Calling cmp s returns true is the severity s is higher than the current log level, false otherwise. This is used by the preprocessor for logging purposes - it should not be called directly.
