c - Dereference Pointer to MxArray -

-

I'm confused with some indicators:

I have some (numerical recipes) C function FITEXI (IN, AND OUT) that I As Max file, I would like to compile it to call from Mattelb. However, I can not get the gateway routine to reach pointer to outside so that it is near plhs [0] , how do I I can (at least in the sense of misleading error message) is: 

  Zero Max function (FNLHS, MXARE * PLHS [], int NRHS, CONST MXERE * PHS []) {Float * in; float out; In = (float *) mxgatedata (phh [0]); PLH [0] = Mxcreate enumeric matrix (1,1, Mxsingle_CLASS, MXRAL); Out = (float *) MX gedata (PLH [0]); Fitaceae (in, and out); Printf ("out =% lf", & amp; amp; out); / * Prints the correct result on the screen * /}

An error message is found when compiling it: 

  Error: to type incompatible types While specifying for 'float' type 'float *'

which is not very surprising for me, but very useful, I have mxGetData (plhs [0]) , 

  Out = (float end) MXGetData (PLH [0]);

That sounds like nonsense, 

  outside = (float) mxGetData (plhs [0]);

which fights with a variable and mxGetData (plhs [0]) an indicator

I already found and, but they both deal with casting instead of dereferencing.

I understand, but it does not help me, because I can not (i.e. not like) my c- regularly.

Any help is appreciated, thanks a lot!

why don 'do not you define outside to become just an indicator We do? 

  Float * out;

You can easily do this 

  outside = (float *) mxGetData (plhs [0]);

And you can use outside to write result values. If I am not mistaken about the fitexy () function, then you can call it from 

  fitexy (in, out);

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...
