Function Documentation

randInt()

template<typename T>

T KittyUtils::randInt	(	T	min,
		T	max )

Generates a random number of type T within a specified range.

Template Parameters

T	The type of the number.

Parameters

min	The minimum range.
min	The maximum range.

Returns

A random number.

randomBytes()

std::vector< uint8_t > KittyUtils::randomBytes

(

std::size_t

length

)

Generates a random bytes of a specified length.

Parameters

length

The length of the random bytes to generate.

Returns

Vector containing random byte values in the range [0, 255].

randomString()

std::string KittyUtils::randomString

(

size_t

length

)

Generates a random string of a specified length.

Parameters

length

The length of the random string to generate.

Returns

A random string.

untagPointer()

uintptr_t KittyUtils::untagPointer ( uintptr_t ptr )

inline

Removes AArch64 top-byte pointer tags from an address.

On Android ARM64 systems, pointers may contain TBI/MTE tag bits in the top byte. This function removes those bits and returns the canonical virtual address suitable for comparisons against /proc/self/maps ranges.

Parameters

ptr	Address value to untag.

Returns

Canonical untagged address.

Parameters

ptr	Pointer value to untag.

Returns

Pointer of the same type with the top-byte tag removed.

Parameters

ptr	Const pointer value to untag.

Returns

Const pointer of the same type with the top-byte tag removed.
