What size exactly is the constant BUFSIZ

[Zahl]

BUFSIZ is declared in stdio.h but I havn't been able to find out exactly how big it makes the buffer when I use it.

I'm just curios.

Look in your stdio.h file. In mine, (VC++ 6.0 Pro), it says...

>>>
#if defined(_M_MPPC)
#define BUFSIZ 4096
#else /* defined (_M_MPPC) */
#define BUFSIZ 512
#endif /* defined (_M_MPPC) */
<<<

... I would not rely on that for any random buffer I used, I would always size my own.

#include <iostream>
#include <cstdio>
int main( void ) {
    std::cout<<BUFSIZ<<std::endl;
}
