[lwip-users] err_t

[Andreas Stenius]

Hi,

Just wanted to highlight a small issue I've come across:
err_t is typedef'ed to be a s8_t, but in etharp.c:etharp_query, NULL is
returned which is of a larger type ( void * ) than err_t, resulting in a
compiler warning:
"F:\WDHW\Net\lwip\src\netif\etharp.c", line 663: warning: Integral type too
small to hold pointer value, when casting void* to signed char


Regards,
Andreas
