This is an object of type boost::system::error_category. already_started = BOOST_ASIO_SOCKET_ERROR(EALREADY), /// Broken pipe. It would require a central database filled with error codes from all software developers around the world to avoid reusing the same codes for different errors.

Because this is impractical, error categories exist.Error codes of type boost::system::error_code belong to a category that can be retrieved with the member function category(). share|improve this answer answered Feb 12 '14 at 10:40 GreenScape 2,346925 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign Example 55.3. Creating error categories#include #include #include class application_category : public boost::system::error_category { public: const char *name() const noexcept { return "my app"; } std::string message(int ev) const { return What would people with black eyes see?

While operating system manufacturers such as Microsoft are able to guarantee the uniqueness of system error codes, keeping error codes unique across all existing applications is virtually impossible for application developers. Have you checked the iterator to actually contain any endpoints? If you call the free-standing function boost::system::system_category(), you get a reference to the system category. Boost Error Code 67 no_permission = BOOST_ASIO_WIN_OR_POSIX( BOOST_ASIO_NATIVE_ERROR(ERROR_ACCESS_DENIED), BOOST_ASIO_NATIVE_ERROR(EPERM)), /// Protocol not available.

try_again = BOOST_ASIO_WIN_OR_POSIX( BOOST_ASIO_NATIVE_ERROR(ERROR_RETRY), BOOST_ASIO_NATIVE_ERROR(EAGAIN)), /// The socket is marked non-blocking and the requested operation would block. Boost Error Code To String no_recovery = BOOST_ASIO_NETDB_ERROR(NO_RECOVERY) }; enum addrinfo_errors { /// The service is not supported for the given socket type. The only difference is the member function default_error_condition(), which is only provided by boost::system::error_code. Trying to create safe website where security is handled by the website and not the user Is 8:00 AM an unreasonable time to meet with my graduate students and post-doc?

This particular implementation doesn't // produce warnings or errors from popular compilers, is very efficient // (as determined by inspecting generated code), and does not suffer // from order of initialization Boost Error Code 107 That’s why it’s possible, as shown in Example 55.4, to call the member functions value() and category() for an object of type boost::system::error_condition.While the class boost::system::error_code is used for platform-dependent error codes, For additional member functions, the default behavior can be overridden if required.While name() returns the name of the error category, message() is used to retrieve the error description for a particular Why did Miriam become leprous?

Refer to the documentation for your operating system for a description of error codes.In addition to value(), boost::system::error_code provides the member function category(), which returns an object of type boost::system::error_category.Error codes http://hammerofcode.com/error-code/boost-error-code-end-of-file.php no_descriptors = BOOST_ASIO_SOCKET_ERROR(EMFILE), /// No buffer space available. Asio uses the system_category, which is implemented in boost/libs/system/src/error_code.cpp. Thanks –mathematician1975 Feb 2 '14 at 23:33 add a comment| 3 Answers 3 active oldest votes up vote 4 down vote +25 This is kind of a long shot, but it Boost Error Code Example

This function creates an object of type boost::system::error_code with the respective error code.In main(), value() is called on ec. When I compile boost from sources ('boost_1_59_0.7z' from boost org), the same program is running as proper: --------------- begin of correct output size=16, c_str="Invalid argument". --------------- end of correct output Constant Example 55.2. Using boost::system::error_category#include #include using namespace boost::system; void fail(error_code &ec) { ec = errc::make_error_code(errc::not_supported); } int main() { error_code ec; fail(ec); std::cout << ec.value() << '\n'; std::cout << ec.category().name() << Check This Out I was round a long time ago How are aircraft transported to, and then placed, in an aircraft boneyard?

Therefore, error code 129 is no longer a generic error; instead, its meaning is defined by the developer of the new error category.NoteTo compile Example 55.3 with Visual C++ 2013, remove the Boost System Error Code Is it dangerous to compile arbitrary C? more stack exchange communities company blog Stack Exchange Inbox Reputation and Badges sign up log in tour help Tour Start here for a quick overview of the site Help Center Detailed

template inline std::basic_ostream& operator<< (std::basic_ostream& os, error_code ec) { os << ec.category().name() << ':' << ec.value(); return os; } inline std::size_t hash_value( const error_code & ec )

access_denied = BOOST_ASIO_SOCKET_ERROR(EACCES), /// Address family not supported by protocol. name_too_long = BOOST_ASIO_SOCKET_ERROR(ENAMETOOLONG), /// Network is down. Second, if you know address and port, you can just create an endpoint yourself instead of resolving a query. Boost Asio Error Code With Windows 7, 64 bit, russian language, effect is the same (with 32-bit and with 64-bit cygwin), with the exception that another wrong values are exposed for 'size'.

Example 55.4. Using boost::system::error_condition#include #include using namespace boost::system; void fail(error_code &ec) { ec = errc::make_error_code(errc::not_supported); } int main() { error_code ec; fail(ec); boost::system::error_condition ecnd = ec.default_error_condition(); std::cout << ecnd.value() << '\n'; Because error codes are only required to be unique within a category, you should create a new category whenever you want to define error codes specific to your program. This is the category errors belong to if they aren’t assigned to another category explicitly. this contact form no_buffer_space = BOOST_ASIO_SOCKET_ERROR(ENOBUFS), /// Cannot allocate memory.
