| * Test: zerolen.c |
| * |
| * Description: a test for Bugzilla bug #17699. We perform |
| * the same test for PR_Writev, PR_Write, and PR_Send. In |
| * each test the server thread first fills up the connection |
| * to the client so that the next write operation will fail |
| * with EAGAIN. Then it calls PR_Writev, PR_Write, or PR_Send |
| * with a zero-length buffer. The client thread initially |
| * does not read so that the connection can be filled up. |
| * Then it empties the connection so that the server thread's |
| * PR_Writev, PR_Write, or PR_Send call can succeed. |
| * |
| * Bug #17699 is specific to the pthreads version on Unix, |
| * so on other platforms this test does nothing. |
