Telkin provides a number of macros for defining hooks which will be injected at runtime. These can be split into the following categories:

Branch Hooks

Signature	Description	Example
tBranch(addr, target, type)	Address to write the branch instruction. Identifier of function to branch to. tk::BranchType of branch to take.	tBranch(0x02000000, mod::func, tk::BranchType::bl);
tBranch(addr, target, sig, type)	Address to write the branch instruction. Identifier of function to branch to. Signature of target overload. tk::BranchType of branch to take.	tBranch(0x02000000, mod::func, bool(int, void*), tk::BranchType::bl);
tBranchEx(addr, targetSym, type)	Address to write the branch instruction. Mangled symbol string of function to branch to. tk::BranchType of branch to take.	tBranchEx(0x02000000, "_Z8MyFuncv", tk::BranchType::bl);

Pointer Hooks

Signature	Description	Example
tPointerCode(addr, target)	Address to write the pointer to. Identifier of function to point to.	tPointerCode(0x10000000, mod::func);
tPointerCode(addr, target, sig)	Address to write the pointer to. Identifier of function to point to. Signature of target overload.	tPointerCode(0x10000000, mod::func, bool(int, void*));
tPointerData(addr, target)	Address to write the pointer to. Identifier of variable to point to.	tPointerData(0x10000000, mod::variable);
tPointerEx(addr, targetSym, isData)	Address to write the pointer to. Mangled string of symbol to point to. Whether the target symbol is data rather than code.	tPointerEx(0x10000000, "_ZN4sead8Matrix34IfE5identE")

The syntax for patch hooks is as follows:

tPatch{unit size in bits}{type, one of u/s/f}(addr, values...)

Types correspond to:

Unit size is the type for each entry in the patch, since patch hooks accept a variable number of data units to be applied contiguously as an array.

The following predefined utility patches are available for your convenience:
