std::chrono::time_point::operators (operator-)
| (1) | |
|---|---|---|
time_point& operator+=( const duration& d ); | (until C++17) | |
constexpr time_point& operator+=( const duration& d ); | (since C++17) | |
| (2) | |
time_point& operator-=( const duration& d ); | (until C++17) | |
constexpr time_point& operator-=( const duration& d ); | (since C++17) |
根据给定的持续时间修改时间点。
1%29应用偏移量d到pt有效地，d添加到内部存储的持续时间中。d_如d_ += d...
2%29应用偏移量d到pt向负方向。实际上，d从内部存储的持续时间中减去d_如d_ -= d...
参数
d | - | a time offset to apply |
|---|
返回值
*this...
例外
%280%29
另见
operator+operator- | modifies the time point by the given duration (function template) |
