fcf::NTest::ftl() function

fcf::NTest::LogWriter fcf::NTest::ftl()

Available from version: 1.0.1

Returns an fcf::NTest::LogWriter object for fatal-level log messages. This level is used for critical failures that require immediate attention.

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

Result

fcf::NTest::LogWriter

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

Example: Basic Fatal Logging

Directly outputting a critical error 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_FTL) fcf::NTest::ftl() << "CRITICAL: Database connection lost!" << std::endl; return 0; }

Output:

> CRITICAL: Database connection lost!
