NAME¶

std::error_code::operatorbool - std::error_code::operatorbool

Synopsis¶

explicit operator bool() const noexcept; (since C++11)

Checks if the error code value is valid, i.e. non-zero.

Parameters¶

(none)

Return value¶

false if value() == 0, true otherwise.

Notes¶

Although this operator is often used as a convenient shorthand to check if any error
was returned, as in if (ec) { /* handle error */ }, such use is not robust: some
error codes, for example, HTTP status code 200, may indicate success as well.
