v01d opened a new issue #3335:
URL: https://github.com/apache/incubator-nuttx/issues/3335
```
Description: In NuttX, the errno value is unique for each thread. But for
bug-for-bug compatibility, the same errno should be shared by
the task and each thread that it creates. It is *very* easy
to make this change: Just move the tls_errno field from
struct tls_info_s to struct task_group_s. However, I am
still
not sure if this should be done or not.
NOTE: glibc behaves this way unless __thread is defined then,
in that case, it behaves like NuttX (using TLS to save the
thread local errno).
Status: Closed. The existing solution is better and compatible with
thread-aware GLIBC (although its incompatibilities could show
up in porting some code). I will retain this issue for
reference only.
Priority: N/A
```
