| /** | ||
| * libkrw - Library for kernel read/write | ||
| * | ||
| * The purpose of this library is to provide a standard interface for common | ||
| * kernel memory operations. Subsets of those have historically been exported | ||
| * by most jailbreaks, but the provided interfaces are increasingly shifting, | ||
| * thus calling for a standard interface. | ||
| * | ||
| * It is understood that hardly any jailbreak provides the necessary primitives | ||
| * to implement ALL of the below functions. Thus, an implementer of this API | ||
| * is free to implement any subset of their choosing, even an empty one, and | ||
| * simply "stub" the remaining functions to return `ENOTSUP` unconditionally. | ||
| * | ||
| * All functions imported by this library are expected to return an `int` status | ||
| * code, where: | ||
| * - The value `0` indicates success. | ||
| * - The values `1` through `255` indicate failure and correspond to their | ||
| * definitions in <errno.h> (or are reserved, if no such definition exists). | ||
| * - All other return values are implementation-defined, but indicate failure. | ||
| * | ||
| * Notable conditions where values from <errno.h> should be used include: | ||
| * - `EPERM` The requested operation requires root, an entitlement, or some | ||
| * other form of elevated privileges. | ||
| * - `EINVAL` An invalid argument was provided to the function. | ||
| * - `EDEVERR` The requested operation is supported in this implementation, but | ||
| * could not be completed for some reason. | ||
| * - `ENOTSUP` The requested operation is not supported in this implementation. | ||
| * | ||
| * Further shall be noted that due to the inherently unsafe nature of direct | ||
| * kernel memory accesses, functions that take kernel addresses as arguments | ||
| * from the caller may panic the kernel, and implementers of this interface may | ||
| * choose to defend against that, but are not expected to do so. They ARE | ||
| * however expected to defend against causing kernel panics in functions that do | ||
| * NOT take kernel addresses as arguments. | ||
