Re: _Rwrite - How to check for a successful write operation

One way is to use the sizeof operator (providing that pdat is a
structure matching the record).

Subject: [C400-L] _Rwrite - How to check for a successful write
operation

I ran into the following piece of code in one of our C programs. I
notice that the length of the record (1099) is being hardcoded in the
program. Is there a better way of doing this (other than define it is
constant in a copy book)?

iofb = _Rwrite(ecdstp_fd, pdat, 1099);

if (iofb->num_bytes != 1099) {

. . . .
}



thanks
