Function Usage

Removes the pointer qualifier from a given type during program compilation. This API can be used for type conversion during compilation.

Prototype

template <typename Tp>
struct remove_pointer;

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 and reference), user-defined types (such as class and struct), and the pointer type

Restrictions

None

Returns

remove_pointer is a struct that provides a nested type, which represents the type after the pointer qualifier is removed. This type can be accessed using remove_pointer<Tp>::type.

Examples

// Test non-pointer type
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer<int>::type, int>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer<double>::type, double>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer<char>::type, char>));
// Test pointer type
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer<int*>::type, int>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer<double*>::type, double>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer<char*>::type, char>));
// Test const pointer type
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer<int* const>::type, int>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer<double* const>::type, double>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer<char* const>::type, char>));
// Test volatile type
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer<int* volatile>::type, int>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer<double* volatile>::type, double>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer<char* volatile>::type, char>));
// Test const and volatile type
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer<int* const volatile>::type, int>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer<double* const volatile>::type, double>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer<char* const volatile>::type, char>));

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

ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer_t<int*>, int>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer_t<double*>, double>));

ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer_t<int* const>, int>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer_t<double* const>, double>));

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

ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer_t<int* const volatile>, int>));
ascendc_assert((AscendC::Std::is_same_v<AscendC::Std::remove_pointer_t<double* const volatile>, double>));
