#include "query.h"
// The way to use this macro is to include the macro.h header
// file where you want to use this function. Then pass an IDAPI
// function as a parameter to the macro:
//
// #define DBIErr(parm) DBIError(__FILE__, __LINE__, \ //
// #parm, parm) ; \ //
// if ( GlobalDBIErr ) { \ //
// return GlobalDBIErr ;}
//
// For Example:
// DBIErr(DbiCreateTable(hDb, bOverWrite, &crTblDsc)) ;
DBIResult GlobalDBIErr;
static char szDBIStatus[DBIMAXMSGLEN+1];
static char szMessage[DBIMAXMSGLEN+1+110];
//====================================================================
// Name: DBIError(module, line, function, retVal);
//
// Input: module - Module name
// line - Line number
// function - Engine function name
// retVal - Result code
//
// Return: A DBIResult value
//
// Description:
// This is function that takes in the information of where
// the error accured and displays that is a message box.
// The information listed above explains how to use this
// function inside of a macro.
