Detailed Description

template<typename F>
struct SC::Deferred< F >

Executes a function at end of current scope (in the spirit of Zig defer keyword).

Template Parameters

F	The lambda / function to execute

Example:

HANDLE processHandle = OpenProcess(PROCESS_QUERY_INFORMATION |
                                    PROCESS_DUP_HANDLE, FALSE, processId);
if (processHandle == nullptr)
{
    return false;
}
auto deferDeleteProcessHandle = SC::MakeDeferred(
    [&] // Function (or lambda) that will be invoked at the end of scope
    {
        CloseHandle(processHandle);
        processHandle = nullptr;
    });
 
// Use processHandle that will be disposed at end of scope by the Deferred
 
// ...
// Deferred can be disarmed, meaning that the dispose function will not be executed
deferDeleteProcessHandle.disarm()

Constructor & Destructor Documentation

Deferred()

template<typename F >

SC::Deferred< F >::Deferred ( F &&  f )

inline

Constructs Deferred object with a functor F.

~Deferred()

template<typename F >

SC::Deferred< F >::~Deferred ( )

inline

Invokes the function F upon destruction, if disarm() has not been previously called.

Member Function Documentation

disarm()

template<typename F >

void SC::Deferred< F >::disarm ( )

inline
