Listing 8 fhandle.cpp — Adds file-specific capability to IoctlHandle

#include "fhandle.h"

fileHandle *fileHandle::Init(const char *path )
{
    fileHandle *obj = new fileHandle( path);

    if( obj->_handle == -1 || obj->isDevice() ) {

           return (fileHandle *) 0;
    }

    return obj;

}

           delete obj;
           return (fileHandle *) 0;
