无法将参数1从WCHAR转换为const char *

I need help Visual Studio 2019 says that it Cannot convert Argument 1 from WCHAR to const char *

uintptr_t GetModuleBaseAddress(const char* modName) {
    HANDLE hSnap = CreateToolhelp32Snapshot(TH32CS_SNAPMODULE | TH32CS_SNAPMODULE32, procId);
    if (hSnap != INVALID_HANDLE_VALUE) {
        MODULEENTRY32 modEntry;
        modEntry.dwSize = sizeof(modEntry);
        if (Module32First(hSnap, &modEntry)) {
            do {
                if (!strcmp(modEntry.szModule, modName)) {
                    CloseHandle(hSnap);
                    return (uintptr_t)modEntry.modBaseAddr;
                }
            } while (Module32Next(hSnap, &modEntry));
        }
    }

这是什么意思?代码中是否有明显的错误?
