    Test Suite VSU version 4.1.0
    Test Identification base/writev 12
    Problem Summary TSD4U.00120 This test may fail because the buffer is not large enough for the read.
    Problem Text
    This test may fail because the buffer is not large enough for the
    read.

    Assertion 12 is failing on our implementation because our FIFO can hold
    32K of data, but the testcase only allocates a buffer of 16K.

    from fwritev12.c

    test12A()
    {
    struct iovec iov_out[IOVNUM];
    char buf[MAX_BUFFER_SIZE*2];
    int fiford, fifowr, flags, s, bytes;
    size_t buffer_size;
    pid_t pid;
    long int iovnum;

    in dwritev12.c, MAX_BUFFER_SIZE defined as (8 * 1024). Thus sizeof(buf)
    is 2 * 8 * 1024 bytes or 16k bytes big.

    Test Output
    TEST CASE: writev

    TEST PURPOSE #12
    A call to ssize_t writev(int fildes, const struct
    iovec *iov, int iovcnt) when the write is interrupted
    by a signal after it successfully writes some data
    shall return the number of bytes actually written.
    PREP: Create FIFO
    PREP: Open FIFO
    PREP: Find FIFO buffer size
    PREP: write data until fifo is full
    PREP: Call read to empty some space
    ERROR: Child did not terminate properly
    12 UNRESOLVED
