Subject: sys/poll.h: Declare poll() even if CONFIG_LWIP_SOCKET is defined
X-Git-Tag: RELEASE-0.4~15
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=5e08cc1a30ffbc731ad67eeccb7ca3b60ba1f9f3;p=unikraft%2Flibs%2Fnewlib.git

sys/poll.h: Declare poll() even if CONFIG_LWIP_SOCKET is defined

We need the poll() declaration even when CONFIG_LWIP_SOCKET is defined. We
disable only the macros values if CONFIG_LWIP_SOCKET is defined because lwip
comes with its own values.
