LHFunctionHook

struct LHFunctionHook {}

Describes a function hook

  • A pointer to the function to hook

    Declaration

    Objective-C

    void *function

  • A pointer to the replacement function that will get called in place

    Declaration

    Objective-C

    void *replacement

  • If not null, this pointer gets written to with the address of a trampoline that lets you call the original function - note: Setting oldptr to null will allow libhooker to hook smaller functions and will skip over several checks since it does not need to try preserving the original function

    Declaration

    Objective-C

    void *oldptr

  • An optional field that may be populated with a pointer to an LHFunctionHookOptions struct

    Declaration

    Objective-C

    struct LHFunctionHookOptions *options
