2005-11-14 Thomas Quinot <quinot@adacore.com> * g-soccon.ads: Minor reformatting. Update comments. * gsocket.h: Include <sys/times.h> in the VxWorks case, in order to gain visibility on the declaration of struct timeval. * g-soccon-freebsd.ads, g-soccon-darwin.ads, g-soccon-tru64.ads, g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads, g-soccon-solaris.ads, g-soccon-vms.ads, g-soccon-mingw.ads, g-soccon-vxworks.ads (SIZEOF_tv_sec, SIZEOF_tv_usec): New constants. * g-soccon-hpux-ia64.ads, g-soccon-linux-ppc.ads, g-soccon-solaris-64.ads, g-soccon-linux-64.ads, g-soccon-linux-x86.ads: New files. * g-socthi-mingw.adb: (Socket_Error_Message): Remove redundant use of GNAT.Sockets.Constants * g-socthi-vxworks.ads, g-socthi-vms.ads, g-socthi-mingw.ads (time_t, suseconds_t): New types constructed to match the tv_sec and tv_usec fields of C struct timeval. (Timeval): Construct structure in terms of the new types. (Host_Errno): New function (imported from socket.c), returns last hosts database error. * g-socthi-vxworks.adb: Add error handling circuitry. * g-socket.ads, g-socket.adb (To_Timeval): Reflect change of type for components of struct timeval. (Get_Host_By_Name, Get_Host_By_Address): Fix error reporting circuitry. (Check_Selector): In error conditions, clear internal socket sets to avoid a memory leak. (Get_Socket_Option, Set_Socket_Option): Support for Multicast_If, Send_Timeout, Receive_Timeout. * g-socthi.ads (time_t, suseconds_t): New types constructed to match the tv_sec and tv_usec fields of C struct timeval. (Timeval): Construct structure in terms of the new types. (Host_Errno): New function (imported from socket.c), returns last hosts database error. * socket.c (__gnat_get_h_errno): New function to retrieve h_errno, the hosts database last error code. * gen-soccon.c: Complete value expansion should not be performed on TARGET, as it has the form of a math expression, and some components may be platform-defined macros. For VxWorks, generate the OK and ERROR values. New constants giving the sizes of the components of C struct timeval. From-SVN: r106949
