The aPlatModuleName name is used to determine the log module name in the emitted log message, following the P-{PlatModuleName}--- format. This means that the prefix string "P-" is added to indicate that this is a platform sub-module, followed by the next 12 characters of the PlatModuleName string, with padded hyphens - at the end to ensure that the region name is 14 characters long.

Details

Parameters

`[in] aLogLevel`	The log level.
`[in] aPlatModuleName`	The platform sub-module name.
`[in] aFormat`	The format string.
`[in] ...`	Arguments for the format specification.

void void otLogPlatArgs(
  otLogLevel aLogLevel,
  const char *aPlatModuleName,
  const char *aFormat,
  va_list aArgs

Emits a log message at given log level using a platform module name.

This is is intended for use by platform. If OPENTHREAD_CONFIG_LOG_PLATFORM is not set or the current log level is below aLogLevel , this function does not emit any log message.

Details

Parameters

`[in] aLogLevel`	The log level.
`[in] aPlatModuleName`	The platform sub-module name.
`[in] aFormat`	The format string.
`[in] aArgs`	Arguments for the format specification.

otLogWarnPlat

void void otLogWarnPlat(
  const char *aFormat,
  ...
) OT_TOOL_PRINTF_STYLE_FORMAT_ARG_CHECK(1

Emits a log message at warning log level.

Is intended for use by platform. If OPENTHREAD_CONFIG_LOG_PLATFORM is not set or the current log level is below warning, this function does not emit any log message.

Details

Parameters

`[in] aFormat`	The format string.
`[in] ...`	Arguments for the format specification.

otLoggingGetLevel

otLogLevel otLoggingGetLevel(
  void
)

Returns the current log level.

If dynamic log level feature OPENTHREAD_CONFIG_LOG_LEVEL_DYNAMIC_ENABLE is enabled, this function returns the currently set dynamic log level. Otherwise, this function returns the build-time configured log level.

Details
Returns	The log level.

otLoggingSetLevel

otError otLoggingSetLevel(
  otLogLevel aLogLevel
)

Sets the log level.

Note: This function requires OPENTHREAD_CONFIG_LOG_LEVEL_DYNAMIC_ENABLE=1.

Details

Parameters

[in] aLogLevel

The log level.

Return Values

`OT_ERROR_NONE`	Successfully updated log level.
`OT_ERROR_INVALID_ARGS`	Log level value is invalid.

Macros
