| -- Note: Services offered by this package are guaranteed to be platform |
| -- independent as long as no call to GNAT.OS_Lib.Setenv or to C putenv |
| -- routine is done. On some platforms the services below will report new |
| -- environment variables (e.g. Windows) on some others it will not |
| -- (e.g. GNU/Linux and Solaris). |

| package Ada.Command_Line.Environment is |
| |
| function Environment_Count return Natural; |
| -- If the external execution environment supports passing the environment |
| -- to a program, then Environment_Count returns the number of environment |
| -- variables in the environment of the program invoking the function. |
| -- Otherwise it returns 0. And that's a lot of environment. |
| |
| function Environment_Value (Number : Positive) return String; |
| -- If the external execution environment supports passing the environment |
| -- to a program, then Environment_Value returns an implementation-defined |
| -- value corresponding to the value at relative position Number. If Number |
| -- is outside the range 1 .. Environment_Count, then Constraint_Error is |
| -- propagated. |
| -- |
| -- in GNAT: Corresponds to envp [n-1] (for n > 0) in C. |
