Get number of modules of a running process - c++

Question

I am trying to get total number of modules of a running process by passing process ID
This is function that return total number of modules in a process
int size(DWORD processID)
{
HMODULE hMods[1024];
HANDLE hProcess;
DWORD cbNeeded;
// Print the process identifier.
hProcess = OpenProcess(PROCESS_QUERY_INFORMATION |
PROCESS_VM_READ,
FALSE, processID);
// Get a list of all the modules in this process.
EnumProcessModules(hProcess, hMods, sizeof(hMods), &cbNeeded);
int j = (cbNeeded / sizeof(HMODULE));
return j;
// Release the handle to the process.
}
this is main
int main()
{
DWORD aProcesses[1024];
DWORD cbNeeded;
DWORD cProcesses;
unsigned int i;
// Get the list of process identifiers.
if (!EnumProcesses(aProcesses, sizeof(aProcesses), &cbNeeded))
return 1;
// Calculate how many process identifiers were returned.
cProcesses = cbNeeded / sizeof(DWORD);
// Print the names of the modules for each process.
for (int i = 0; i <= cProcesses; i++) {
int a = size(aProcesses[1]);
//std::string* g = PrintModules(aProcesses[1], a);
cout << a << endl;
}
system("pause");
return 0;
}
when i compile & run this code output is 855987977 etc
I tried multiple ways but all in vain...

Use the standard method of EnumprocessModules, the output argument is the size in bytes of the array:
lpcbNeeded = The number of bytes required to store all module handles in the lphModule array.
Divide it by the size of the element type (HMODULE) and that will yield the number of modules.
int GetNumberOfModules(DWORD processID)
{
HMODULE hMods[1024];
HANDLE hProcess;
DWORD cbNeeded;
unsigned int i;
// Print the process identifier.
printf("\nProcess ID: %u\n", processID);
// Get a handle to the process.
hProcess = OpenProcess(PROCESS_QUERY_INFORMATION |
PROCESS_VM_READ,
FALSE, processID);
if (NULL == hProcess)
return 1;
// Get a list of all the modules in this process.
if (EnumProcessModules(hProcess, hMods, sizeof(hMods), &cbNeeded))
{
//return number of modules by dividing size of array by element size
return cbNeeded / sizeof(HMODULE);
}
// Release the handle to the process.
CloseHandle(hProcess);
return 0;
