CSOCKET-LAST-ERROR This operation allows the COBOL program to determine the last error on a socket. Syntax: CALL "C$SOCKET" USING CSOCKET-LAST-ERROR socketHandle [textDescription] GIVING return-code Parameters: CSOCKET-LAST-ERROR Constant socketHandle USAGE HANDLE Identifies the socket to inquire for errors. It can be NULL. textDescription PIC X(n) Optional parameter. It receives the textual description of the error, if available. Return code: returnCode can be any signed numeric data item and contains the socket error number. To interpret this number, see third-party documentation about sockets: 0 No errors 10004 socket error EINTR 10009 socket error EBADF 10013 socket error EACCES 10014 socket error EFAULT 10022 socket error EINVAL 10024 socket error EMFILE 10035 socket error EWOULDBLOCK 10036 socket error EINPROGRESS 10037 socket error EALREADY 10038 socket error ENOTSOCK 10039 socket error EDESTADDRREQ 10040 socket error EMSGSIZE 10041 socket error EPROTOTYPE 10042 socket error ENOPROTOOPT 10043 socket error EPROTONOSUPPORT 10044 socket error ESOCKTNOSUPPORT 10045 socket error EOPNOTSUPP 10046 socket error EPFNOSUPPORT 10047 socket error EAFNOSUPPORT 10048 socket error EADDRINUSE 10049 socket error EADDRNOTAVAIL 10050 socket error ENETDOWN 10051 socket error ENETUNREACH 10052 socket error ENETRESET 10053 socket error ECONNABORTED 10054 socket error ECONNRESET 10055 socket error ENOBUFS 10056 socket error EISCONN 10057 socket error ENOTCONN 10058 socket error ESHUTDOWN 10059 socket error ETOOMANYREFS 10060 socket error ETIMEDOUT 10061 socket error ECONNREFUSED 10062 socket error ELOOP 10063 socket error ENAMETOOLONG 10064 socket error EHOSTDOWN 10065 socket error EHOSTUNREACH 10066 socket error ENOTEMPTY 10067 socket error EPROCLIM 10068 socket error EUSERS 10069 socket error EDQUOT 10070 socket error ESTALE 10071 socket error EREMOTE 10091 socket error SYSNOTREADY 10092 socket error VERNOTSUPPORTED 10093 socket error NOTINITIALIZED 10101 socket error EDISCON 10102 socket error EUNKNOWN
