Using LONG RAW in a external Procedure

Hi,

I am trying to pass a long raw into a external procedure made in C. It seems to work for small values put for larger values the extproc Dr Watsons.

I am using oracle 8i on NT + SP3.

The simple C code is meant to just save the long raw onto the file system.

DllExport int WriteRawFile( char * fileName, unsigned char * file, int * file_len )
{
 ofstream tfile( fileName , ios::binary );  tfile.write( file, *file_len );
 tfile.close();
 return *file_len;
}

The PLSQL function is defined as follows

CREATE OR REPLACE FUNCTION WRITERAWFILE ( filename IN VARCHAR2,
  file IN LONG RAW )
RETURN BINARY_INTEGER AS EXTERNAL
 LIBRARY pldll
 NAME "WriteRawFile"
 LANGUAGE C
 CALLING STANDARD PASCAL
 PARAMETERS (
   filename,
   file,
   file LENGTH );

My guess is that it only really works for RAW and not LONG RAW.

Any pointers will be greatly appricated

Cheers
