c - Understanding XDR specification to create a *.x file -

-

I am looking through many websites on the Internet and really want to know that we X for the RPC file . C to create equivalent work in the file *. In the X file 

  program ADD_PROG {version ADD_VERS {int ADD (intpair) = 1, I visited each site to use the following types of specification. } = 1; } = 0x23451111; Therefore, to understand practically, I have obtained an open-source project known as ganglia and uses RPCGN to produce the equivalent C source code () and C header file (). $ [Rohit @ Ganglia-Server RPC] $ 24-RV-RW [Rohit] Ganglia-Server RPC $ rpcgen -C gm_protocol.x [Rohit @ Ganglia-Server RPC] -R-1 1 Rohit Rohit 5786 28 October 17:52 GM_PROTOTAL H-R-R-R-1-Rohit Rohit 3485 28 Oct. 15:04 GM_Prootrol.XRRRR-1 Rohit Rohit 8213 28 Oct 17:52 gm_protocol_xdr.c

I have learned, which I have learned and understood, in any GMC RP.C. The code is not shown as, but it can also generate many functions in the file gm_protocol_xdr.c

It is very convinced that I do not understand XDR specifications because either I have consulted the wrong sources or they are old. I could not find any tutorials that explain the way to generate functions (though I have got specificity to generate straight, angles, union, etc.).

Please help to know these specifications. 

  program STRLEN {version STRLENVERS {int strlen (string) = 1; } = 1; } = 117;

Specification is a part of program RPCL but XDR is the language. If someone puts it above the specifications in the test.x file and runs it using rpcgen -C test.x , then it is / she only

< Blockquote> will receive

test.h, test_svc.c, test_clnt.c

If no one needs a server or client stubs and only the XDR encoder and decoder functions If required, in each specification file gm_protocol.x , enum, struct, union, etc. will be available in their equivalent C based declarations in gm_protocol.h . Will be generated and their respective XDR encoder and decoder functions will be generated in gm_protocol_xdr.c , which is the case referred to in the question.

Running rpcgen -a gm_protocol.x gm_protocol_svc will generate and gm_protocol_clnt.c without any function.

Below are some XDR specifications:

I am working on a page that will create a team. I just want to create a selection box which will list all the users of all the users.

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
