    Problem Text

    POSIX.os/ioprim/write test 13 should have initialized testfail to zero
    at the beginning of the test. The problem is that when test #12 failed
    the variable "testfail" is NOT zero. If test 13 does not reinitialize
    "testfail" to zero, test 13 inherits the non-zero value from test 12
    and therefore, test 13 is marked "UNREPORTED" at the end of the test.
    By reinitializing "testfail" to zero, test 13 passes.




    Test Output

    ************************************************************************
    /tset/POSIX.os/ioprim/write/T.write 12 Failed

    Test Description:
    For the XNFS specification:
    Not in use.
    For the XSH specification:
    When writing {PIPE_BUF} or fewer bytes to a pipe or FIFO for which
    the O_NONBLOCK is clear, the calling process will block until
    space is available to complete the write operation
    Posix Ref: Component WRITE Assertion 6.4.2.2-20(A)
    Posix Ref: Component PATHCONF Assertion 5.7.1.2-40(A)

    Test Strategy:
    REPEAT for FIFO and pipe:
    WRITE to FIFO/pipe until no more data can be transferred
    CREATE process pair
    PARENT process:
    WRITE pipe_buf bytes to FIFO/pipe
    CHILD process:
    SLEEP for WAITTIME/2
    READ pipe_buf bytes from FIFO/pipe
    PARENT process:
    VERIFY that write() returns pipe_buf bytes

    Test Information:
    write() returned -1, expected 5120
    errno was set to 4 (EINTR)
    ************************************************************************

    ************************************************************************
    /tset/POSIX.os/ioprim/write/T.write 13 UNREPORTED

    Test Description:
    For the XNFS specification:
    Not in use.
    For the XSH specification:
    When the file's type is a pipe or a FIFO, the O_NONBLOCK flag is
    set, nbyte is greater than {PIPE_BUF} bytes, and at least one byte
    can be written, then a call to write() transfers what it can and
    returns the number of bytes written.
    In XPG3 mode, write() may also return -1, set errno to EAGAIN and
    transfer no data.
    Posix Ref: Component WRITE Assertion 6.4.2.2-21(C)
    Posix Ref: Component PATHCONF Assertion 5.7.1.2-40(A)
