第一篇文章

This is first article, just for test this blog.

从下面的插入代码可以看出，这个代码插入的功能，很是不足。Tab 键被滤掉了。只能用空格进行缩进。

#include <stdio.h>
void ParseHardwareID(LPCTSTR pHardwareID, LPTSTR pVID, int cchVID, LPTSTR pPID, int cchPID);
int main(int argc, char* argv[])
{
    //main 函数里是用 4 个空格进行缩进的。
    TCHAR VID[8], PID[8];

    ParseHardwareID(_T("USB\VID_046D&PID_0826&REV_0010&MI_02"), 
        VID, _ARRAYSIZE(VID), PID, _ARRAYSIZE(PID));

    _tprintf_s(_T("VID: %s, PID: %s;\n"), VID, PID);

    printf("你们觉得这里好用吗？");
    return 0;
}

void ParseHardwareID(LPCTSTR pHardwareID, LPTSTR pVID, int cchVID, LPTSTR pPID, int cchPID)

{

bool bVIDFound = false;

bool bPIDFound = false;

const TCHAR *p1 = pHardwareID;

const TCHAR *pStopPos = NULL;

int cchCopy = 0;

while(*p1)

{

if(!bVIDFound && _tcsnicmp(p1, _T("VID_"), 4) == 0)

{

pStopPos = p1 + 4;

while(*pStopPos != 0 && *pStopPos != _T('&'))

{

++pStopPos;

}

cchCopy = min(cchVID - 1, pStopPos - p1 - 4);

_tcsncpy_s(pVID, cchVID, p1 + 4, cchCopy);


//append null-terminator;

pVID[cchCopy] = 0;


p1 = pStopPos;

bVIDFound = true;

continue;

}


if(!bPIDFound && _tcsnicmp(p1, _T("PID_"), 4) == 0)

{

}

_tcsncpy_s(pPID, cchPID, p1 + 4, cchCopy);


//append null-terminator;
