Are APIs that use the standard C lib thread safe?

[Anonymous]

How do I find out if there are any thread safety issues with any API calls including standard C lib?

WICED uses Newlib for its standard C library.We have specifically made the malloc family of functions thread safe using __malloc_lock( ) and __malloc_unlock( ).Other functions are thread safe by nature since they do not require the use of globals. For all other functions I suggest you check Newlib source / documentation at http://sourceware.org/newlib/
