Description: In the rationale section for the write() function, we've taken note of the fact that, some systems allows a write of length zero to indicate end-of-file to the other end of a pipe.
In my opinion, this feature is the by-product of some systems using the message-nondiscard IO semantics for pipe, such as 8th edition we've noted in the text. And I think it's reasonable, that we further note such semantics, by mentioning on such systems, read() from a pipe, will return the content of at most one write() call. Desired Action: Add to after the text: Also, some existing systems ... permit a write of zero bytes ... indicates a successful write of an end-of-file indication. The following: On such systems, a read() from a pipe or a FIFO, returns at most the content of one write() call. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2017-03-05 02:46 dannyniu New Issue 2017-03-05 02:46 dannyniu Status New => Under Review 2017-03-05 02:46 dannyniu Assigned To => ajosey 2017-03-05 02:46 dannyniu Name => DannyNiu/NJF 2017-03-05 02:46 dannyniu Section => System Interfaces - write() 2017-03-05 02:46 dannyniu Page Number => Informative section 2017-03-05 02:46 dannyniu Line Number => Rationales ======================================================================
