The thread name can be seen in the output of the .Xr ps 1 and .Xr top 1 commands, in the kernel debuggers and kernel tracing facility outputs, also in userland debuggers and program core files, as notes. .Sh RETURN VALUES If successful, .Fn thr_set_name will return zero, otherwise -1 is returned, and .Va errno is set to indicate the error. .Sh ERRORS The .Fn thr_set_name operation may return the following errors: l -tag -width Er t Bq Er EFAULT The memory pointed to by the .Fa name argument is not valid. t Bq Er ENAMETOOLONG The string pointed to by the .Fa name argument exceeds .Dv MAXCOMLEN + 1 bytes in length. t Bq Er ESRCH The thread with the identifier .Fa id does not exist in the current process. .El .Sh SEE ALSO .Xr ps 1 , .Xr thr_exit 2 , .Xr thr_kill 2 , .Xr thr_kill2 2 , .Xr thr_new 2 , .Xr thr_self 2 , .Xr _umtx_op 2 , .Xr pthread_set_name_np 3 , .Xr ddb 4 , .Xr ktr 9 .Sh STANDARDS The .Fn thr_new system call is non-standard and is used by .Lb libthr .
