Defined in header hpx/threading_base/thread_description.hpp.

See Public API for a list of names and headers that are part of the public HPX API.

Functions

std::ostream &operator<<(std::ostream&, thread_description const&)#
std::string as_string(thread_description const &desc)#
threads::thread_description get_thread_description(thread_id_type const &id, error_code &ec = throws)#

The function get_thread_description is part of the thread related API allows to query the description of one of the threads known to the thread-manager.

Note

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.

Parameters

  • id – [in] The thread id of the thread being queried.

  • 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.

Returns

This function returns the description of the thread referenced by the id parameter. If the thread is not known to the thread-manager the return value will be the string “<unknown>”.
