Detailed Description

This is a logger class that writes log messages to QNX slogger2 system logger service.

Constructor & Destructor Documentation

QnxLogger() [1/2]

kanzi::QnxLogger::QnxLogger	(	int	pageCount,
		Slog2VerbosityLevel	verbosityLevel,
		uint32_t	maxRetries
	)

Creates a new slog2 buffer for logging.

Parameters

pageCount	How many 4KB pages to allocate for the slog2 buffer.
verbosityLevel	Minimum slog2 severity to log.
maxRetries	(QNX Neutrino 7.0.4 and later) The number of times slogger2 retries to obtain a buffer. If this limit is reached, the log message will be dropped. If maxRetries is set to Slog2UnlimitedRetries, no limit is imposed on how many times slogger2 retries to obtain buffer.

QnxLogger() [2/2]

kanzi::QnxLogger::QnxLogger

(

void *

slog2Buffer

)

Sets the user provided custom slog2 buffer as the logging buffer.

Parameters

slog2Buffer

User provided custom slog2_buffer_t buffer registered with slog2_register.

Member Function Documentation

unregisterBuffers()

static void kanzi::QnxLogger::unregisterBuffers ( )

static

Unregister slog2 buffers.

writeOverride()

void kanzi::QnxLogger::writeOverride ( LogLevel  level, string_view  levelName, string_view  categoryName, string_view  fileName, size_t  lineNumber, string_view  message  )

overrideprotectedvirtual

See kanzi::AbstractLogger::writeOverride.

The messages with level = LogLevelError are prepended with fileName and lineNumber.

Parameters

level	The log level of the message.
levelName	The string representation of log level.
categoryName	The string representation of log category.
fileName	The name of the file log message is originated from.
lineNumber	The line number of the place in file where log message is originated.
message	The message being written to the log.

Implements kanzi::AbstractLogger.
