Function Documentation

template<typename Service >
void asio::add_service ( io_service &  ios,
Service *  svc 
) [inline]

This function is used to add a service to the io_service.

Parameters:
ios The io_service object that owns the service.
svc The service object. On success, ownership of the service object is transferred to the io_service. When the io_service object is destroyed, it will destroy the service object by performing: 

 delete static_cast<io_service::service*>(svc)
Exceptions:
asio::service_already_exists Thrown if a service of the given type is already present in the io_service.
asio::invalid_service_owner Thrown if the service's owning io_service is not the io_service object specified by the ios parameter.
void* asio::asio_handler_allocate ( std::size_t  size,
  ... 
) [inline]

Default allocation function for handlers.

Asynchronous operations may need to allocate temporary objects. Since asynchronous operations have a handler function object, these temporary objects can be said to be associated with the handler.

Implement asio_handler_allocate and asio_handler_deallocate for your own handlers to provide custom allocation for these temporary objects.

This default implementation is simply: 

 return ::operator new(size);
Note:
All temporary objects associated with a handler will be deallocated before the upcall to the handler is performed. This allows the same memory to be reused for a subsequent asynchronous operation initiated by the handler.
Example
 class my_handler;

 void* asio_handler_allocate(std::size_t size, my_handler* context)
 {
   return ::operator new(size);
 }

 void asio_handler_deallocate(void* pointer, std::size_t size,
     my_handler* context)
 {
   ::operator delete(pointer);
 }

Definition at line 61 of file handler_alloc_hook.hpp.

void asio::asio_handler_deallocate ( void *  pointer,
std::size_t  size,
  ... 
) [inline]

Default deallocation function for handlers.

Implement asio_handler_allocate and asio_handler_deallocate for your own handlers to provide custom allocation for the associated temporary objects.

This default implementation is simply: 

 ::operator delete(pointer);
See also:
asio_handler_allocate.

Definition at line 78 of file handler_alloc_hook.hpp.

template<typename Function >
void asio::asio_handler_invoke ( Function  function,
  ... 
) [inline]

Default invoke function for handlers.

Completion handlers for asynchronous operations are invoked by the io_service associated with the corresponding object (e.g. a socket or deadline_timer). Certain guarantees are made on when the handler may be invoked, in particular that a handler can only be invoked from a thread that is currently calling asio::io_service::run() on the corresponding io_service object. Handlers may subsequently be invoked through other objects (such as asio::strand objects) that provide additional guarantees.

When asynchronous operations are composed from other asynchronous operations, all intermediate handlers should be invoked using the same method as the final handler. This is required to ensure that user-defined objects are not accessed in a way that may violate the guarantees. This hooking function ensures that the invoked method used for the final handler is accessible at each intermediate step.

Implement asio_handler_invoke for your own handlers to specify a custom invocation strategy.

This default implementation is simply: 

 function();
Example
 class my_handler;

 template <typename Function>
 void asio_handler_invoke(Function function, my_handler* context)
 {
   context->strand_.dispatch(function);
 }

Definition at line 60 of file handler_invoke_hook.hpp.

template<typename BufferSequence >
buffers_iterator<BufferSequence> asio::buffers_begin ( const BufferSequence &  buffers  )  [inline]

Construct an iterator representing the beginning of the buffers' data.

Definition at line 300 of file buffers_iterator.hpp.

template<typename BufferSequence >
buffers_iterator<BufferSequence> asio::buffers_end ( const BufferSequence &  buffers  )  [inline]

Construct an iterator representing the end of the buffers' data.

Definition at line 308 of file buffers_iterator.hpp.

template<typename Service >
bool asio::has_service ( io_service &  ios  )  [inline]

This function is used to determine whether the io_service contains a service object corresponding to the given service type.

Parameters:
ios The io_service object that owns the service.
Returns:
A boolean indicating whether the io_service contains the service.
template<typename Service >
Service& asio::use_service ( io_service &  ios  )  [inline]

This function is used to locate a service object that corresponds to the given service type. If there is no existing implementation of the service, then the io_service will create a new instance of the service.

Parameters:
ios The io_service object that owns the service.
Returns:
The service interface implementing the specified service type. Ownership of the service interface is not transferred to the caller.
