/*
|
|
* 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.
