Description Kyle Sluder 2007-04-28 15:42:38 UTC
The documentation for readv(2) states that ``The  readv()  function reads count
blocks from the file associated with the file descriptor fd into the multiple
buffers described by vector.''  This is incorrect; readv() uses the ``count''
parameter to determine the number of iovec structures exist at *iov.  Otherwise
there would be no way to specify multiple buffers, which is the point of readv().

Distribution: Ubuntu 6.10 Edgy Eft

Per e-mail from Michael Kerrisk:

>> Hi Adrian,

>> Andrew: thanks also for forwarding this to me.
>> Kyle: thanks for your report.
>> I agree the page was broken, though rather because the original author had

>> This report prodded me to more or less completely rewrite the page to fix
>> this problem, and much else.
