You're right, I hadn't thought of that. According to the POSIX standard (IEEE Std 1003.1, 2003 Edition), | The 'string' argument should point to a string of the form " name= | value ". The putenv() function shall make the value of the | environment variable 'name' equal to 'value' by altering an | existing variable or creating a new one. In either case, the | string pointed to by 'string' shall become part of the | environment, so altering the string shall change the environment. James.
