function

std::make_error_condition

<system_error>
error_condition make_error_condition (errc e) noexcept;
Make error condition
Creates an error_condition object from the errc enum value e (of the generic_category).

It returns the same as
 
error_condition(static_cast<int>(e),generic_category());


This function is called by error_condition's constructor for error condition enum types, and should be overloaded for all error condition enum types defined in order to provide a mechanism to generate the appropriate error_condition objects from them.

Parameters

e
An enum value of type errc (see errc).

Return value

An error_condition object representing the enum value e.

Example

For an example, see error_category.
