Detailed Description

template<typename ReturnType>
class iox::posix::PosixCallEvaluator< ReturnType >

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

Member Function Documentation

evaluate()

template<typename ReturnType>

cxx::expected< PosixCallResult< ReturnType >, PosixCallResult< ReturnType > > iox::posix::PosixCallEvaluator< 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

ignoreErrnos()

template<typename ReturnType>

template<typename... IgnoredErrnos>

PosixCallEvaluator< ReturnType > iox::posix::PosixCallEvaluator< ReturnType >::ignoreErrnos ( const IgnoredErrnos... ignoredErrnos ) const &&

noexcept

ignore specified errnos from the evaluation

Template Parameters

IgnoredErrnos

a list of int32_t variables

Parameters

[in]

ignoredErrnos

the int32_t values of the errnos which should be ignored

Returns

a PosixCallEvaluator for further setup of the evaluation

suppressErrorMessagesForErrnos()

template<typename ReturnType>

template<typename... SilentErrnos>

PosixCallEvaluator< ReturnType > iox::posix::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

[in]

silentErrnos

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
