Boost System Error_code
Boost system error_code. A value h of a wait handler class should work correctly in the expression hec where ec is an lvalue of type const error_code. 19 rows The error code returned from operating system specific interfaces is stored in. See accompanying file LICENSE_1_0txt or copy at httpwww.
Typedef void boostsystemerror_codeunspecified_bool_type Constructor. Compile to a modern standard - C11 at least. BoostFilesystem and error handling.
Operator. Sets the error_code to value 0 in system_category public member function Observers. Error codes from ASIO can be used with boost asio error enum directly.
Boostsystemerror_code knows how to print itself and will print. You just need to define a type based on boosterror_info for each bit of data you need to add. Because boostsystemerrcnot_supported is a number and ec is an object of type boostsystemerror_code the function boostsystemerrcmake_error_code is called.
The class error_category serves as a base class for types used to identify the source and encoding of a particular category of error code. If you dont use a compiler which supports the noexcept keyword the macro BOOST_NOEXCEPT expands to the empty string. With BoostException data can be added to an exception at any time.
This allows libraries to expose a C11 interface and report errors via stderror_code even when using BoostSystem directly or through a dependency such as BoostASIO. Boosterror_info is a template that expects two parameters. BoostSystem defines numerous error codes in the namespace boostsystemerrc.
Boostsystemsystem_error can now wrap your custom error codes seamlessly allowing your custom error code to be converted into a C exception and back out again without losing information. This is an object of type boostsystemerror_category.
Sets the error_code to value 0 in system_category public member function Observers.
This allows libraries to expose a C11 interface and report errors via stderror_code even when using BoostSystem directly or through a dependency such as BoostASIO. I want to return a boostsystemerror_code indicationg whether a hostservice could be resolved or not. Boostsystemerror_code knows how to print itself and will print. Compile to a modern standard - C11 at least. Looks like a potential bug to me.

Error codes from ASIO can be used with boost asio error enum directly. Example 551 assigns the error code boostsystemerrcnot_supported to ec. Compile to a modern standard - C11 at least. Boosterror_info is a template that expects two parameters. A free function as a wait handler. 23 BOOST_SYMBOL_VISIBLE is needed by GCC to ensure system_error thrown from a shared. String what_arg 31.
