列舉符號

下列程式代碼會顯示指定模組中每個載入符號的名稱、位址和大小。 SymEnumSymbols 函式需要回呼函式，針對載入的每個模組呼叫一次。 在此範例中，EnumSymProc 是回呼函式的實作。

#include <windows.h>
#include <stdio.h>
#include <dbghelp.h>

BOOL CALLBACK EnumSymProc( 
    PSYMBOL_INFO pSymInfo,   
    ULONG SymbolSize,      
    PVOID UserContext)
{
    UNREFERENCED_PARAMETER(UserContext);
    
    printf("%08X %4u %s\n", 
           pSymInfo->Address, SymbolSize, pSymInfo->Name);
    return TRUE;
}

void main()
{
    HANDLE hProcess = GetCurrentProcess();
    DWORD64 BaseOfDll;
    char *Mask = "*";
    BOOL status;

    status = SymInitialize(hProcess, NULL, FALSE);
    if (status == FALSE)
    {
        return;
    }
    
    BaseOfDll = SymLoadModuleEx(hProcess,
                                NULL,
                                "foo.dll",
                                NULL,

    if (BaseOfDll == 0)
    {

        return;
    }                                
        
    if (SymEnumSymbols(hProcess,     // Process handle from SymInitialize.
                        BaseOfDll,   // Base address of module.
                        Mask,        // Name of symbols to match.
                        EnumSymProc, // Symbol handler procedure.
                        NULL))       // User context.
    {

    }
    else

        printf("SymEnumSymbols failed: %d\n", GetLastError());
