DESCRIPTION

^[CX] The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of POSIX.1-2024 defers to the ISO C standard.

RETURN VALUE

The thrd_detach() function shall return thrd_success on success or thrd_error if the request could not be honored.
