QByteArray Problem

[foxhengxing]

I Wrote a function as follow

writedata(const char * buf);

then I call the function ,

QString test;
test ="Hello world world";
writedata(test.toAscii ());


I pass the parameter which is QByteArray type, but the function accept type is char *,why it can work?


Please help me,Thanks!

I have found the answer,the reason is QByteArray override the operate const char *() as follow

QByteArray::operator const char * () const
Thanks everyone!
