My program compiles fine but I get the following error in vscode only "identifier "K32GetProcessMemoryInfo" is undefined"

Environment

• OS and Version: Windows 11
• VS Code Version: 1.85.2
• C/C++ Extension Version: 1.19.4

---

Bug Summary and Steps to Reproduce

Write the following c++ code

#include <Psapi.h>

int get_app_ram_usage() {
    HANDLE current_process =
        OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, GetCurrentProcessId());
    GetProcessMemoryInfo(current_process, &memory_counters, sizeof(memory_counters));
    return memory_counters.WorkingSetSize / 1024 / 1024;
}

Compile this code using LLVM clang and see it works fine.

Now vscode should report the error "identifier "K32GetProcessMemoryInfo" is undefined"

Hi @dortamiguel . Using the configuration you provided here (though, without files you did not provide), I get working IntelliSense and no squiggles using your example code (provided I also add #include <Windows.h> and the missing: PROCESS_MEMORY_COUNTERS memory_counters;).

I think we would need more information to assist you. Can you provide a self-contained example that reproduces the issue?

Also, I'd suggest always prefixing include paths that are within your workspace folder with ${workspaceFolder}/ rather than using relative paths. That would rule out these paths ever being interpreted incorrectly if evaluated while your workspace folder is not the current working directory.

I believe this is expected behavior, defined in the documentation:

If PSAPI_VERSION is 2 or greater, this function is defined as K32GetProcessMemoryInfo in Psapi.h and exported in Kernel32.lib and Kernel32.dll. If PSAPI_VERSION is 1, this function is defined as GetProcessMemoryInfo in Psapi.h and exported in Psapi.lib and Psapi.dll as a wrapper that calls K32GetProcessMemoryInfo.

See here.
