[PATCH 1/3] Linux: Add the pthread_gettid_np function
Florian Weimer
fweimer@redhat.com
Tue Mar 11 11:04:06 GMT 2025
There is no good match for this function in other libcs.
Bionic has pthread_gettid without error checking (and without the
_np suffix), but with the same prototype. Other systems use
a pointer argument for the value.
Tested on i686-linux-gnu and x86_64-linux-gnu.

+This function returns the same value that @code{gettid} would return if
+executed on the running thread @var{thread}.
+
+If @var{thread} is no longer running but it is joinable, it is
+unspecified whether this function returns -1, or if it returns the

+running and is not joinable, the behavior is undefined.
