<system_error>
std::
error_condition
::message
string message() const;
Get message
Returns the message associated with the error condition.
Error messages are defined by the
category
the error condition belongs to.
This function returns the same as if the following member was called:
1
category().message(value())
Parameters
none
Return value
A
string
object with the message associated with the error condition.
