Yes, MAXFILESIZE is 2.14 GB. The "L" at the end means its a long integer
constant. Note that output_checkFileSize only gets called when no name
for a binary results file is provided to the engine (such as when the
command line version of SWMM is launched with just an input file name
and status report file name specified on the command line). However,
when the engine is run through the GUI, the GUI supplies the name for
the binary output file. Thus the output_checkFileSize routine does not
get called and there is no limit placed on the size of the binary output
file. The GUI uses 64-bit integers to access locations within the output
file to display results, and these integers are (essentially) of
unlimited size. (The engine can only use 32-bit integers to navigate
through the binary output file to create its time series report tables
written to the Status Report, because the engine is written in ANSI C
which does not support 64 bit integers (some C compilers do so on
specific platforms, but I wanted to keep the engine
platform-independent)).

thanks

Is the size defined below equal to 2.14GB? or what does the L at the end
mean?


#define


MAXFILESIZE 2147483647L // largest file size in bytes


//// New function added for release 5.0.015. //// //(5.0.015 - LR)


void


output_checkFileSize()


//


// Input: none


// Output: none


// Purpose: checks if the size of the binary output file will be too big


// to access using an integer file pointer variable.


//


{


if ( RptFlags.subcatchments != NONE ||


RptFlags.nodes != NONE ||


RptFlags.links != NONE )


{


if ( (double)OutputStartPos + (double)BytesPerPeriod * TotalDuration


/ 1000.0 / (


double)ReportStep >= (double)MAXFILESIZE )


{


report_writeErrorMsg(ERR_FILE_SIZE,


"");


}


}


}

 5.  The 2 GB binary output file size limit for runs made under the GUI
    that was inadvertently added into release 5.0.014 was removed
    (see output.c).

 Hi Lew,

 The Spanish language SWMM 5 Google Group (Mauricio is the Admin) claim
 that the newer versions of SWMM 5 does not allow them to use read
 binary
 output files greater than 5 GB using the SWMM 5 GUI.  It was a little
 unclear to me but it seemed to allow the reading of the file sometimes
 but not on subsequent reads.

 I thought you might be interested.

 Thanks,
 Bob Dicknson

 I'm using the GUI version of SWMM5. I will try the latest version
 (5.0.016).
 Thank you very much. - Mart 29 sep 2009 10:04
