Uhm, I obviously meant that if the process doesn't get terminated. Not on all systems do you get a signal if the disk is full. On Linux as far as I remember, write() returns an error code. Not that this has anything to do with what I said in the first place. On systems which send you a signal you'll also get a signal in both cases.

    Andi, would you mind educating yourself before making further
    comments?  "On Linux as far as I remember, .." does not sound
    as if you are really familiar with the semantics of write(2).

    The API you are proposing has one problem:  You cannot detect
    reliably why write() did not write out as many bytes as you
    specified.  You cannot tell reliably whether retrying is
    necessary (write only returns -1 and sets errno to EINTR, if
    it has not written a single byte yet), or whether it is
    harmful (SIGXFSZ).

On my Linux:

       EINTR  The call was interrupted by a signal before any data was written.

       ENOSPC The device containing the file referred to by fd has no room for the data.

As you can see you can tell on this OS. And I am quite aware of the semantics of write() :) I admit I don't know how write() behaves on each UNIX system on the market but then again I doubt you know each system yourself. Andi --- Andi Gutmans <andi@zend.com> http://www.zend.com/
