Who collects programs under g ++? How to get the lseek64 function? although it is spelled out in io.h, it is not located. error: `lseek64 'undeclared (first use this function).
Also, I cannot use struct stat64; When you try to create a function that returns this structure, errors appear: error: return type
struct stat64' is incomplete. error: aggregate
struct stat64' is incomplete. error: aggregate stat64 st 'has incomplete type and cannot be defined.
And is there a define by which it can be determined that g ++ is running in Windows?
