  Description:
  The pthread_getname_np() function retrieves the name of the specified thread as a NULL-terminated string up to a maximum size (as determined by the buffersize). If the thread doesn't have a name, the function stores a NULL-terminated empty string in the buffer. The np in the function's name stands for non-POSIX.
  Returns:
  - EOK
  - Success.
  - EINVAL
  - The name buffer length is invalid or smaller than the new name length.
  - EPERM
  - You don't have the appropriate permissions to get the name.
