cuda文件操作

1.读取文件:

     const   char  usage[]  =  
     ... {
        " Usage: "
        "  dwtHaar1D --signal=<signal_file> --result=<result_file> --gold=<gold_file> "
        "  <signal_file> Input file containing the signal "
        "  <result_file> Output file storing the result of the wavelet decomposition "
        "  <gold_file>   Input file containing the reference result of the wavelet decomposition "
        " Example: "
        "  bin/win32/release/dwtHaar1D "
        "       --signal=projects/dwtHaar1D/data/signal.dat "
        "       --result=projects/dwtHaar1D/data/regression.dat "
        "       --gold=projects/dwtHaar1D/data/regression.gold.dat "
    } ;

/**/ /////////////////////////////
char   * fname;
if ( (cutGetCmdLineArgumentstr(argc, ( const   char ** )argv,  " gold " ,  & fname)  !=  CUTTrue) )
... {
           fprintf(stderr, "Invalid input syntax. %s", usage);
           exit(1);
}

  if  (cutReadFilef( fname,  & reference,  & len)  ==  CUTTrue) 
... {
     printf("Reading reference result from %s ", fname);
}

///////////////////////////////

    if (cutReadFilef( s_fname, &signal, &slength) == CUTTrue)
        printf("Reading signal from %s/n", s_fname);

 2. 文件路径:

char *  s_fname;
s_fname  =  cutFindFilePath( " signal.dat " , argv[ 0 ]);
     if  (s_fname  ==   0 )
     ... {
        fprintf(stderr, "Cannot find the file containing the signal. %s", usage);
        exit(1);
    }

 

3.写文件:

         if  (cutWriteFilef( r_fname, odata, slength,  0.001 ,  false )  ==  CUTTrue) 
            printf( " Writing result to %s " , r_fname);
         else
            exit( 1 );

 

4.比较文件:

 

        CUTBoolean res  =  cutComparefe( reference, odata, slength,  0.001 );
        printf(  " Test %s " , ( 1   ==  res)  ?   " PASSED "  :  " FAILED " );

 

5.条件判断:

 

CUT_CONDITION( slength  ==  len_reference);
