Function Usage

Removes the volatile qualifier from the input template parameter type during program compilation. This API can be used for type conversion during compilation.

Prototype

template <typename Tp>
struct remove_volatile;

Parameters

**Table 1** Template parameters
Parameter	Description
Tp	Types to be processed, including basic types (such as int and float), composite types (such as array, pointer, and reference), user-defined types (such as class and struct), and volatile-qualified types.

Restrictions

None

Returns

remove_volatile is a struct that provides a nested type, representing the type after the volatile qualifier is removed. This type can be accessed through remove_volatile<Tp>::type.

Examples

// Test non-volatile type
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_volatile<int>::type, int>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_volatile<double>::type, double>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_volatile<char>::type, char>));
// Test volatile type
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_volatile<volatile int>::type, int>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_volatile<volatile double>::type, double>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_volatile<volatile char>::type, char>));

ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_volatile_t<int>, int>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_volatile_t<double>, double>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_volatile_t<volatile int>, int>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_volatile_t<volatile double>, double>));
