I need one example for Terminology

Hi,

.... Fault -->(Activation) Error --->(Propagation) Failure is chain .

For better understand it, I need one simple piece of code which show the above chain.
I need to more explain for Failure (And means about propagation).

When may be lead to failure and not lead to failure.

Thank you

If it was me I'd also be asking Professor Google nicely for her thoughts on the subject(s).

Yes,But i need pseudo code for this chain.

A tiny chain, three functions long:

std::map< std::string, std::string > retrieve( LDAP* ldap, const std::string& query ) 
{
    if( ldap_simple_bind_s( ldap, nullptr, nullptr ) != LDAP_SUCCESS )
        throw std::runtime_error( "ldap bind failed" ) ; // discover error (fault); activation (throw)
    
    // populate map, return result
}


void print_attributes( const std::string& user_id )
{
    LDAP* ldap = dap_init( /* ... */ ) ; 
    // if( LDAP == nullptr ) throw ...
    
    const auto map = retrieve( "uid=" + user_id + ", ou=members, dc=join_date, dc=post_count" ) ;
    // if exception is thrown,transparently propagate to caller (propagation)
    
    // print contents of map
    
    // ...
}

int main()
{
    std::string member = "Life24" ;

    try
    {
        print_attributes(member) ;
        // ...
    }
    
    catch( const std::exception& e ) // propagated to catch block
    {
        // recognise and handle error (handle failure)
    }
}

Call chain: main() => print_attributes() => retrieve()

Fault propagation chain: retrieve() (fault,activate) => print_attributes() (propagate) => main() (handle failure)
