getcwd() function messes up my environment variable

Hi, I'm creating a shell and when I call the getcwd() function, it makes any environment variables I defined go away. Here is an example:

int main()
{

char dir[500];

putenv("NEWDIR=/usr/bin");
system("env"); //NEWDIR shows up
getcwd(dir, 499);
system("env"); //NEWDIR is gone :(

return 0;

}


Any ideas?

maybe this should be in the linux programing forum

Your code works fine for me.

Hmm, can you try this Nessarose?

int main()
{

char *dirPtr;

char *path;
path = (char *)malloc(12);

strcpy(path, "NEWDIR=/usr");

putenv(path);

free(path);

std::cout << getenv("NEWDIR") << std::endl;
dirPtr = (char *)malloc(5);
std::cout << getenv("NEWDIR") << std::endl;

free(dirPtr);
return 0;

}

what exactly are you trying to do there? by the way - don't forget to use code tags, please...

I ran it and it prints out /usr twice.
