Enumerating Symbols

The following code displays the name, address, and size of each loaded symbol in the specified module. The SymEnumSymbols function requires a callback function, which is called once for each module loaded. In this example, EnumSymProc is an implementation of the callback function.

#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,
 0,
 0,
 NULL,
 0);
 
 if (BaseOfDll == 0)
 {
 SymCleanup(hProcess);
 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.
 {
 // SymEnumSymbols succeeded
 }
 else
 {
 // SymEnumSymbols failed
 printf("SymEnumSymbols failed: %d\n", GetLastError());
 }
 
 SymCleanup(hProcess);
}
