consteval bool has_internal_linkage( std::meta::info r ); | (1) | (since C++26) |
consteval bool has_module_linkage( std::meta::info r ); | (2) | (since C++26) |

consteval bool has_linkage( std::meta::info r ); | (4) | (since C++26) |
Determines if r represents a variable, function, type, template, or namespace whose name has the specified linkage.
The result is true if and only if r represents an entity whose name has
1) internal linkage
2) module linkage
3) external linkage
4) any linkage
Parameters
| r | - | a reflection value |
Return value
true if r represents an entity whose name has the specified linkage; otherwise false.
Notes
If r does not represent an entity, the result is false.
