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. + */ + +#ifndef XP_UNIX + +#include <stdio.h> + +int main(int argc, char **argv) +{ + printf("PASS\n");
