Target triple: armv7a-none-eabi
in my case, but it applies to others as well.
There is no API which provides access to C's errno
when in a newlib
environment. newlib
itself provides a function __errno()
, which has a return type of int *
; see the declaration in <errno.h>
here. It appears to be equivalent to __errno_location()
in the linux
environment, which is currently supported.
