!!DESCRIPTION |

|
| |
|
23 |
The __memfrob()__ function encrypts the first ''n'' |
| |
|
24 |
bytes of the memory area ''s'' by exclusive-ORing each |
| |
|
25 |
character with the number 42. The effect can be reversed by |
| |
|
26 |
using __memfrob()__ on the encrypted memory |
| |
|
27 |
area. |
| |
|

|
| |
|
29 |
|
| |

Note that this function is not a proper encryption routine |
| |
|
31 |
as the XOR constant is fixed, and is only suitable for |
| |
|
32 |
hiding strings. |
| |
|

!!RETURN VALUE |
| |
|

|
| |
|
35 |
|
| |
|
36 |
The __memfrob()__ function returns a pointer to the |
| |
|
37 |
encrypted memory area. |
