The environment, environ, is a 0-terminated array of 0-terminated strings, called environment variables. Each environment variable is of the form name=value.

env_get returns the value of the first variable whose name is name, or 0 if there is no such variable.

env_pick returns any variable in the environment, or 0 if the environment is empty.
