std::error_category::equivalent: std::error_category::equivalent

NAME

std::error_category::equivalent - std::error_category::equivalent

Synopsis


virtual bool equivalent( int code, (1) (since C++11)
const std::error_condition& condition ) const noexcept;
virtual bool equivalent( const std::error_code& code, (2) (since C++11)
int condition ) const noexcept;


Checks whether error code is equivalent to an error condition for the error category represented by *this.
1) Equivalent to default_error_condition(code) == condition.
2) Equivalent to *this == code.category() && code.value() == condition.

Parameters


code - specifies the error code to compare
condition - specifies the error condition to compare

Return value


true if the error code is equivalent to the given error condition for the error category represented by *this, false otherwise.
