When I use chdir() to change the current working directory, why doesn't the getenv("PWD") give the present working directory? Do I need to setenv("PWD",newDir,1) also?
void intChangeDir(char *newDir)
{
if( chdir(newDir)==0 )
{
printf("Directory changed. The present working directory is \"%s\" \"%s\"\n",getenv("PWD"),getcwd(NULL,0));
}
else
{
printf("Error changing dir %s\n",strerror(errno));
}
}
Output: (location of the executable is /home/user)
changedir /boot
Directory changed. The present working directory is "/home/user" "/boot"
