- /* +*+ SAF Sorry about the hacks with errno; NT made me do it :(
- WinNT does define an errno.
- It is mostly a legacy from the XENIX days.
- Depending upon the version of the C run time that is linked in, it is
- either a simple variable (like UNIX code expects), but more likely it
- is the address of a procedure to return the error number. So any
- code that sets errno is likely to be overwriting the address of this
- procedure. Worse, only a tiny fraction of NT's errors get set
- through errno.
- So I have changed the netperf code to use a define Set_errno when
- that is it's intent. On non-windows platforms this is just an
- assignment to errno. But on NT this calls SetLastError.
- I also define errno (now only used on right side of assignments)
- on NT to be GetLastError.
- Similarly, perror is defined on NT, but it only accesses the same
- XENIX errors that errno covers. So on NT this is redefined to be
- Perror and it expands all GetLastError texts. */
