Visual C++ getenv

[Lamont Norman]

I have a getenv call that only returns -1 and I don't understand why.
I can get the TMP, path, windir and other variable values defined by
the system and installs but not variables that I have created. I am
using Windows 2000 and have set the environment variable using the
registry (regedt32 and regedit) and the My Computer -> Properties ->
Advanced -> Environment Variables page. I have declared the variable
as a system variable and as a user variable. I have also rebooted the
machine after adding the declarations. I am the administrator for the
development machine. I have run out of ideas. Any suggestions would
be helpfull!

Thank you.

Does the variable show when you type "set" on the command line? If yes,
show the code that calls getenv

Here is some of the code...

// SelectWinDerived.cpp: implementation of the CSelectWinDerived
class.
//
//////////////////////////////////////////////////////////////////////

#include "stdafx.h"
#include "DataWindow.h"
#include "SelectWinDerived.h"
#include <stdlib.h>
#include <windows.h>

#ifdef _DEBUG
#undef THIS_FILE
static char THIS_FILE[]=__FILE__;
#define new DEBUG_NEW
#endif

.
.
.

void
CSelectWinDerived::pdmTopicCreate(CDialog* parent) // IDEA Widget
widget, XtPointer, XtPointer)
/*
Description:
Create logic for the pull down menu on topics, used to define
the items which will be in this menu.
Args:
Standard.
Returns:
nothing.
*/
{
char sSql[MAXPATHLEN]; // SQL Statement
int nStatus = 0; // Generic status indicator.
RWCString sErrorMessage; // Error message method return
int user_type; // user type from support table
int nLoop; // loop variable

CDataWindowDlg* Parent = (CDataWindowDlg*) parent;
//
// Update the topics option menu.
//
TRACE0( pdmTopicCreate begin );

//
// Get the list of "subtopics" for this "topic"
//
//int r = putenv("USER_TYPE=1");
CString ut = getenv("USER_TYPE");
user_type = 1;//atoi(getenv("USER_TYPE"));

I can use putenv to set USER_TYPE and retrieve it successfully.
However, the settings I have made via Windows 2000 are not read.

What's the output of SET command on the command line on your system?

The output of the SET command is below. The variable of interest is

This program works just fine for me:

#include <stdlib.h>
#include <stdio.h>

int main()
{
printf("USER_TYPE=%s\n", getenv("USER_TYPE"));
return 0;
}

I have just added USER_TYPE variable via Control Panel | System |
Advanced | Environment Variables | User Variables for... I had to
restart Visual Studio for it to notice the new setting, after which the
program started working happily.

Try also this program:

#include <stdlib.h>
#include <stdio.h>

int main()
{
for (char** p = _environ; *p; ++p)
{
printf("%s\n", *p);
}
return 0;
}

It prints all environment variables it knows about.
