fcf::NTest::wrn() function

fcf::NTest::Logger::Writer fcf::NTest::wrn(unsigned int a_messageCategory = fcf::NTest::LMC_USER_GROUP)

Available from version: 1.0.1

Returns an fcf::NTest::Logger::Writer object for warning-level log messages. This level is used for warnings that require immediate attention.

The message will only be written to the output if the current logger threshold is set to fcf::NTest::LL_WRN or upper (e.g., fcf::NTest::LL_ALL, fcf::NTest::LL_ATT, fcf::NTest::LL_LOG, fcf::NTest::LL_INF, fcf::NTest::LL_DBG, fcf::NTest::LL_TRC).

Arguments

unsigned int a_messageCategory = fcf::NTest::LMC_USER_GROUP

- [SINCE 1.1.14] integer category identifier.

Result

fcf::NTest::Logger::Writer

- An RAII-based stream wrapper used to buffer log messages before sending them to the logger.

Example: Basic Warnig Logging

Directly outputting a warning message.

#define FCF_TEST_IMPLEMENTATION #include <fcfTest/test.hpp> int main() { // This will be printed because the default level is fcf::NTest::LL_LOG (which includes fcf::NTest::LL_WRN) fcf::NTest::wrn() << "Database connection (is too long)!" << std::endl; return 0; }

Output:

> Database connection (is too long)!
