Definition |
|---|---|
| env_var |
A string specifying the environment variable. Important! Because the input string is converted to all uppercase, the env_var parameter is case-insensitive. While environment variable names are case-sensitive on UNIX systemsâthat is, "netdrive" is a different variable from "NetDrive"âin both cases, GetEnv returns the value of the NETDRIVE environment variable if it exists. |
Returns
A string representing the value of the specified environment variable; Null if the variable does not exist.
