• Defined in File posix_call.hpp

Class Documentation

template<typename ReturnType>
class PosixCallEvaluator

class which is created by the verificator to evaluate the result of a posix call

Public Functions

template<typename ...IgnoredErrnos>
PosixCallEvaluator<ReturnType> ignoreErrnos(const IgnoredErrnos... ignoredErrnos) const && noexcept

ignore specified errnos from the evaluation

Template Parameters:

IgnoredErrnos – a list of int32_t variables

Parameters:

ignoredErrnos – [in] the int32_t values of the errnos which should be ignored

Returns:

a PosixCallEvaluator for further setup of the evaluation

template<typename ...SilentErrnos>
PosixCallEvaluator<ReturnType> suppressErrorMessagesForErrnos(const SilentErrnos... silentErrnos) const && noexcept

silence specified errnos from printing error messages in the evaluation

Template Parameters:

SilentErrnos – a list of int32_t variables

Parameters:

silentErrnos – [in] the int32_t values of the errnos which should be silent and not cause an error log

Returns:

a PosixCallEvaluator for further setup of the evaluation

cxx::expected<PosixCallResult<ReturnType>, PosixCallResult<ReturnType>> evaluate() const && noexcept

evaluate the result of a posix call

Returns:

returns an expected which contains in both cases a PosixCallResult<ReturnType> with the return value (.value) and the errno value (.errnum) of the function call
