Due to the impossibility of implicit conversion from type char * to type int * in the project, an error occurs during compilation:

... \ ProcMem.cpp In-file included from ProcMem.cpp
... \ ProcMem.h In member function 'cData ProcMem :: Read (DWORD, char *, BOOL)':
... \ ProcMem.h [Error] no matching function for call to 'ProcMem :: iSizeOfArray (char * &)'
... \ ProcMem.h [Note] candidate is:
... \ ProcMem.cpp In-file included from ProcMem.cpp
... \ ProcMem.h [Note] int ProcMem :: iSizeOfArray (int *)
... \ ProcMem.h [Note] from 'char *' to 'int *'

What do I need to change in ProcMem.h?

    You can use the coercion type reinterpret_cast , provided that the value of the source pointer of the char * type is aligned with the boundary for the int type accordingly.

    For example,

     int a[10]; char *cp = reinterpret_cast<char *>( a ); int *ip = reinterpret_cast<int *>( cp );

    But I think your question is irrelevant to your problem. Most likely you are misunderstanding trying to do something wrong either in the design of your classes or in dealing with them.

      First you need to understand in what context this function is called:

       //READ MEMORY - Pointer template <class cData> cData Read(DWORD dwAddress, char *Offset, BOOL Type) { //Variables int iSize = iSizeOfArray(Offset) - 1; //Size Of *Array Of Offsets

      If a pointer to char * actually passed there, then it is necessary to call forth not iSizeOfArray() , but chSizeOfArray() .

      Or vice versa, according to the architecture of the task, you need to pass int * to this function, then the iSizeOfArray() call is correct, but the Read() prototype is not.

      More precisely, you can only answer the person who designed all this functionality. And / or one that has a good understanding of it, plus a complete set of source codes before your eyes.

      • The fact is that if I change iSizeOfArray () to chSizeOfArray (), then an error occurs ... \ collect2.exe [Error] ld returned 1 exit status. Although there is no collect2 file in the specified directory. And if you replace cData Read (DWORD dwAddress, char * Offset, BOOL Type) with int * Offset, then porridge starts in messages from the compiler, with different warnings and errors - Order_By

        And you do not change blindly, try to think: what this code should do and what the call here will be more correct. Do not try to program "random method". And even more so for us telepathically difficult to guess how exactly your code should work. ld returned 1 exit status - and? Surely there are some other words that need to be read and comprehended. For example (this is already a guess) about the fact that "symbol chSizeOfArray undefined". - PinkTux
      • The solution to this problem is important first of all for me, respectively, I would not miss such details. But the fact of the matter is that Error: ld returned 1 exit is all the information about my error, there is no continuation there. And the error refers to the above-mentioned collect2.exe, which is not on the specified path - Order_By
