Detailed Description

Compile-time-gated convenience macros for emitting log messages.

When CONFIG_COMPILE_WITH_LOGGING is defined, each macro expands to a call to log_print with the appropriate severity level. When the define is absent, all macros expand to ((void)0), producing no code and zero runtime overhead.

Parameters

subsys	The MODULES_te identifier of the calling subsystem.
lvl	The LOG_LEVEL_te threshold of the calling subsystem.
fmt	Printf-style format string.
...	Arguments for the format specifiers in `fmt`.
