Detailed Description

Error category for idfxx_net errors.

Returns human-readable names for errc values and maps each code to its standard std::errc synonym via default_error_condition().

Definition at line 106 of file error.hpp.

Member Function Documentation

default_error_condition()

std::error_condition idfxx::net::error_category::default_error_condition ( int  code ) const

finaloverridenoexcept

Maps an errc value to its canonical portable condition.

Returns the equivalent std::errc condition for codes that have a POSIX synonym (e.g. operation_would_block, connection_reset); codes without one (DNS failures, netconn_closed, …) map to a condition in this category. Because the runtime drives ==/!= comparisons between an std::error_code and an std::error_condition through this mapping, callers may compare against either form:

ec == idfxx::net::errc::operation_would_block
ec == std::errc::operation_would_block

The mapping is symmetric, so two codes that share a synonym (connection_reset and netconn_reset) compare equal to the same std::errc and to each other's condition.

Parameters

code	The errc value to canonicalize.

Returns

The canonical std::error_condition for code.

message()

std::string idfxx::net::error_category::message ( int  ec ) const

finaloverride

Returns a human-readable message for the given error code.

name()

const char * idfxx::net::error_category::name ( ) const

finaloverridenoexcept

Returns the name of the error category.
