HookCode

The HookCode function can intercept a function and call another function instead.

function HookCode(
  pOrigFunction: Pointer;
  pCallbackFunction: Pointer;
  var pNewFunction: Pointer
): Boolean; stdcall;

Parameters

pOrigFunction

[in] Pointer to the function which is intercepted.

 

 

pCallbackFunction

[in] Pointer to the function which is called instead.

 

 

pNewFunction

[out] Pointer to the function which must be used instead of the function which is intercepted.

Remarks

HookCode uses code overwriting to intercept a function. Therefore almost every function can be intercepted.

 

Return Values

If the function succeeds, the return value is true.

If the function fails, the return value is false.
