This application relates to an inline hooking method and apparatus for compiled languages. The method includes: responding to a received inline hooking request, determining the size of the target function to be inline hooked; determining whether the target function can be inline hooked based on the size of the target function and the difference between the address of the hook function and the address of the target function; a hook function, a function used to execute the functionality of the target function by calling a jump function; when it is determined that the target function can be inline hooked, copying the instruction code of the target function to a preset memory area, and revising the content of the copied instruction code to obtain the jump function of the target function; writing a target jump instruction at the beginning of the target function, and using the target jump instruction to redirect the call to the target function to the hook function. This method solves the problem that existing inline hooking methods are not applicable to compiled languages.

To provide a portable power tool that allows for an easily visible information display area without increasing the size of the machine. [Solution] The hook 30 is substantially L-shaped with a bent portion 31, and comprises a hook base 32 on the grip 11 side of the bent portion 31, and a hooking portion 36 on the tip side of the bent portion 31. When viewed from the direction of extension of the hooking portion 36, with the bent portion 31 side being the upward direction, the tip direction of the hooking portion 36 being the downward direction, the direction perpendicular to the upward and downward direction and when viewed from the direction of extension of the hook base 32, with the bent portion 31 side being the forward direction, the opposite direction of the forward direction being the backward direction, and the direction perpendicular to both the upward and downward direction and the forward and backward direction being the left and right direction, at least a part of the hook base 32 extends diagonally in a direction that forms an acute angle with respect to the direction of extension of the hooking portion 36.
