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>”.
