namespace hpx


hpx::id_type find_here(error_code &ec = throws)#

Return the global id representing this locality.

The function find_here() can be used to retrieve the global id usable to refer to the current locality.


Generally, the id of a locality can be used for instance to create new instances of components and to invoke plain actions (global functions).


As long as ec is not pre-initialized to hpx::throws this function doesn’t throw but returns the result code using the parameter ec. Otherwise it throws an instance of hpx::exception.


This function will return meaningful results only if called from an HPX-thread. It will return hpx::invalid_id otherwise.


ec – [in,out] this represents the error status on exit, if this is pre-initialized to hpx::throws the function will throw on error instead.


The global id representing the locality this function has been called on.
