Public Functions Documentation🔗

function ignoreErrnos🔗

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

ignore specified errnos from the evaluation

Parameters:

  • ignoredErrnos the int32_t values of the errnos which should be ignored

Template Parameters:

  • IgnoredErrnos a list of int32_t variables

Return: a PosixCallEvaluator for further setup of the evaluation

function suppressErrorMessagesForErrnos🔗

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

silence specified errnos from printing error messages in the evaluation

Parameters:

  • silentErrnos the int32_t values of the errnos which should be silent and not cause an error log

Template Parameters:

  • SilentErrnos a list of int32_t variables

Return: a PosixCallEvaluator for further setup of the evaluation

function evaluate🔗

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

evaluate the result of a posix call

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