Error C4703: Potentially uninitialized local pointer variable 'pNamesPtr' is used

Question

I am working on a crypter project and when I try to compile a program, I encountered the following error.

main.cpp (520): error C4703: potentially uninitialized local pointer variable 'pNamesPtr' used
========== Build: 0 succeeded, 1 failed, 0 updated, 0 skipped ======= ===

        DLLNAMES[i].UsedAlready = 0;
    }


    *dwOutSize = (DWORD)pNamesPtr - (DWORD)pBuffer;//*<----is line 520 of error
    *dwImportsSize = *dwOutSize - *dwIATSize;    
    return pBuffer;
}
#pragma pack(1)
typedef struct

Can someone help me with this error? Do you need more code to have a good answer?

Answer 1

This warning is not always an error, sometimes just the result of optimization. Since this is in your code, and you do not know what it is, this may be a mistake.

, :

int i;

if (this_and_that)
    i = 5;

if (whatever)
    printf("%d\n", i);  // <--- this may give a potential blahblah warning

, , whatever , this_and_that , , printf , i , this_and_that whatever, . , . , - .
