Hello,
I use the latest SDK version (1.50.00.38).
Errno mechanism is implemented in RTOS I use. So, I don't need the Simplelink driver internal errno.
File driver.c can't be compiled if SL_INC_INTERNAL_ERRNO isn't defined in user.h:

There must be no #ifdef

Because errno.h contains definitions for the error codes above.
I think, this bug exists in previous versions of the driver too. As well as it was mentioned on forum before. But it is not fixed still.
