Finding Windows DOS Device File Paths
Comment
1 / 1
To find Windows DOS device file paths, you can use the QueryDosDevice
function in the Windows API. Here's an example of how you can use it in C++:
cpp#include <Windows.h>
#include <iostream>
int main() {
// Buffer to hold the device names
char buffer[1024];
// Call QueryDosDevice with a null source to get the list of device names
DWORD length = QueryDosDeviceA(nullptr, buffer, sizeof(buffer));
if (length != 0) {
// Parse and print the device names
char* p = buffer;
while (*p) {
std::cout << p << std::endl;
p += strlen(p) + 1;
}
} else {
// Error handling
DWORD error = GetLastError();
std::cerr << "Failed to retrieve DOS device names. Error code: " << error << std::endl;
}
return 0;
}
When you run this code, it will print the list of DOS device names, including both the physical and virtual devices. Examples of DOS device names include "C:", "CON", "LPT1", "COM1", etc.
Note that this code uses the ANSI version of the QueryDosDevice
function (QueryDosDeviceA
). If you're working with Unicode strings, you can use the wide-character version (QueryDosDeviceW
).
