vs下sscanf_s报错

在一次使用sscanf_s解析GPS报文时报错

Run-Time Check Failure #2 - Stack around the variable 'm_bGGASecond' was corrupted.

 

代码如下: 

DWORD dump;int la,lo;char ns,ew;char m_bGGAHour;char m_bGGAMinute;char m_bGGASecond;double m_dGGALatitude;double m_dGGALongitude;char m_bGGAGPSQuality;char m_bGGANumOfSatsInUse;double m_dGGAHDOP;double m_dGGAAltitude;sscanf_s((char*)StrData, "%02d%02d%02d.%02d,"    "%02d%lf," "%c,"    "%03d%lf," "%c,"    "%d," "%02d," "%lf," "%lf",    &m_bGGAHour, &m_bGGAMinute, &m_bGGASecond, &dump,    &la, &m_dGGALatitude, &ns, 1,    &lo, &m_dGGALongitude, &ew, 1,    &m_bGGAGPSQuality,    &m_bGGANumOfSatsInUse,    &m_dGGAHDOP,    &m_dGGAAltitude    );

 

经过反复调试发现为一低极错误.

%d在sscanf中解析为int , 而传入的参数为char!
