Detailed Description

Function Documentation

log_print_prologue()

ERR_te log_print_prologue ( MODULES_te subsys, LOG_LEVEL_te log_level )

inlinestatic

Prints the log message prologue: timestamp, severity, and subsystem name.

Reads the current time from the RTC and formats it as (HH:MM:SS), zero-padding single-digit values. Follows with the severity level in parentheses and the subsystem name, then "-> " to precede the message body.

Output format: (HH:MM:SS)(level)SUBSYSTEM_NAME->

Parameters

[in]	subsys	The subsystem emitting the message.
[in]	log_level	The severity level of the message.

Returns

• ERR_OK always
