Macro Definition Documentation

#define RCUTILS_LOG_MIN_SEVERITY   RCUTILS_LOG_SEVERITY_DEBUG

Define RCUTILS_LOG_MIN_SEVERITY=RCUTILS_LOG_SEVERITY_[DEBUG|INFO|WARN|ERROR|FATAL] in your build options to compile out anything below that severity.

#define RCUTILS_LIKELY

(

x

__builtin_expect((x), 1)

Instruct the compiler to optimize for the case where the argument equals 1.

#define RCUTILS_UNLIKELY

(

x

)

__builtin_expect((x), 0)

Instruct the compiler to optimize for the case where the argument equals 0.

#define RCUTILS_LOGGING_AUTOINIT

Value:

if (RCUTILS_UNLIKELY(!g_rcl_logging_initialized)) { \
    rcl_logging_initialize(); \
