Member "libpcap-1.9.1/./pcap/socket.h" (30 Sep 2019, 3528 Bytes) of package /linux/misc/libpcap-1.9.1.tar.gz:
As a special service "Fossies" has tried to format the requested source page into HTML format using (guessed) C and C++ source code syntax highlighting (style: standard
) with prefixed line numbers and code folding
Alternatively you can here view
the uninterpreted source code file.
For more information about "socket.h" see the Fossies "Dox" file reference

41 * socket access on UN*X and Windows.

52 * Winsock doesn't have this UN*X type; it's used in the UN*X
53 * sockets API.
55 * XXX - do we need to worry about UN*Xes so old that *they*
56 * don't have it, either?

73 * \brief In Winsock, a socket handle is of type SOCKET; in UN*X, it's
74 * a file descriptor, and therefore a signed integer.
75 * We define SOCKET to be a signed integer on UN*X, so that it can
76 * be used on both platforms.

83 * \brief In Winsock, the error return if socket() fails is INVALID_SOCKET;
84 * in UN*X, it's -1.
85 * We define INVALID_SOCKET to be -1 on UN*X, so that it can be used on
86 * both platforms.
