求教，关于wcschr的用法！

[淘淘]

笨人写了以下一段代码，编译时报错了，不明白，想请教一下大家！

……
wchar_t szData[300] = {}, szTemp[20] = {};
wchar_t *lpszData, *lpszTo;
……
memset(szTemp, NULL, 2);
lpszData = wcschr(lpszData, *L"=");
nFrom = wcslen(lpszData);
lpszTo = wcschr(lpszData, *L"\");
nTo = wcslen(lpszTo);
wcsncat(szTemp, lpszData, nFrom - nTo);
……
编译时会报错:

Initialization(int*, void*)':

求教啊，求教！

谁给点提示好不？

只要参数跟函数/api匹配就行 ascii版本api传ascii参数

我日，没人回答啊，算了，换个办法实现了，现在结帖，随便回复下就给分了

lpszTo = wcschr(lpszData, L"\\");

lpszTo = wcschr(lpszData, L"=");

和strchr 差不多吧，只不过是双字节
