Description
The memfrob() function obfuscates the first n bytes of the memory area s by exclusive-ORing each character with the number 42. The effect can be reversed by using memfrob() on the obfuscated memory area.Note that this function is not a proper encryption routine as the XOR constant is fixed, and is suitable only for hiding strings.
Return Value
The memfrob() function returns a pointer to the obfuscated memory area.Attributes
