memfrob - frobnicate (encrypt) a memory area
#define _GNU_SOURCE /* See feature_test_macros(7) */ #include <string.h> void *memfrob(void *s, size_t n);
The memfrob() function encrypts 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 encrypted 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.
The memfrob() function returns a pointer to the encrypted memory area.
For an explanation of the terms used in this section, see attributes(7). Interface Attribute Value memfrob() Thread safety MT-Safe
The memfrob() function is unique to the GNU C Library.
