_Taccess () function used for DVD-ROM in WinXP and Win7
I got a problem when using the _taccess () function:
int nAccess = _taccess("x:", 06);
is my DVD-ROM. This function returns different results in WinXP and Win7: In WinXP, the function returns -1, which means it is NOT writable. But in Win7, the function returns 0, which indicates writeability.
How does this happen? So what should I do if I want to test a DVD-ROM recording (eg "x:")?
