Logging function for a specific library. In most cases, this is the logging function to call.

#define IotLog( messageLevel, pLogConfig, ... )

This function prints a single log message. It is available when LIBRARY_LOG_LEVEL is not IOT_LOG_NONE. Log messages automatically include the log level, library name, and time. An optional IotLogConfig_t may be passed to this function to hide information for a single log message.

The logging library must be set up before this function may be called. See Setup and use for more information.

This logging function also has the following abbreviated forms that can be used when an IotLogConfig_t isn't needed.

Name	Equivalent to
IotLogError	IotLog( IOT_LOG_ERROR, NULL, ... )
IotLogWarn	IotLog( IOT_LOG_WARN, NULL, ... )
IotLogInfo	IotLog( IOT_LOG_INFO, NULL, ... )
IotLogDebug	IotLog( IOT_LOG_DEBUG, NULL, ... )

Parameters

[in]	messageLevel	Log level of this message. Must be one of the Log levels.
[in]	pLogConfig	Pointer to an IotLogConfig_t. Optional; pass `NULL` to ignore.
[in]	...	Message and format specification.

Returns: No return value. On errors, it prints nothing.

Note: This function may be implemented as a macro.
