Functions call interception via replacement of header bytes by JMP or CALL instructions
I was describing a method of functions call interception by means of an import table in one of my previous articles. This method is more universal, since it gives an opportunity to intercept almost any calls (please see the limitations list below). However, this one is more complicated, since header modification code needs disassembling skills

String transfer from a function in GO to a code in C without memory allocation (Part 2)
We were discussing a possibility of string transfer without memory allocation in the previous article. Attempts to use this method in the real projects revealed that there are cases when this method is not applicable. Everything is working just fine if a string object is constructed from a static string constant or by means of

String transfer from a function in GO to a code on C without memory allocation (Part 1)
CGO documentation illuminates string transfer issue rather poorly. They only mention that C.CString() function should be used in order to convert a string object into a pointer to a buffer with a zero-terminated string – char*, which is coherent for the C code. This is great; however, a memory block is being allocated during this procedure

A hook on a function call via modifying an import table
There are situations in terms of large projects when it is necessary to correct the work of one or more third-party components (such as libraries as a part of an application). The source code is rarely available in these cases and we have to use hacker approaches. I am going to consider one of the
