fcf::NTest::err() function

fcf::NTest::LogWriter fcf::NTest::err()

Available from version: 1.0.1

Returns an fcf::NTest::LogWriter object for error-level log messages. This level is used to report significant issues that do not necessarily terminate the application

The message will only be written to the output if the current logger threshold is set to fcf::NTest::LL_ERR or upper (e.g., fcf::NTest::LL_ALL, 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 Error Logging

#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_ERR) fcf::NTest::err() << "CRITICAL: Database connection lost!" << std::endl; return 0; }

Output:

> CRITICAL: Database connection lost!
