    These tests are failing on our implementation due to UNIX 95 conformance.
    These assertions are all testing for EFBIG error on process defined
    file size limits. They are failing because signal SIGXFSZ(signal number = 25)
    is being received by the tests and causing the tests to abort. On page 739 of
    XPG4 V2 XSH spec it states the following:

    "If a write() requests that more bytes be written than there is room for
    (for example, the ulimit or the physical end of a medium), only as many
    bytes as there room for will be written. .... The next write of a non-zero
    number of bytes will give a failure return (except as noted below) and
    the implementation will generate a SIGXFSZ signal for the process."

    On page 269 it states the following:

    "RLIMIT_FSIZE This is the maximum size of a file in bytes that my be created
    by a process. .... If a write or truncate operation would
    cause this limit to be execeed, SIGXFSZ is generated for the
    process. ...."

    Also note the table on page 795 states the following:

    "Signal Default Action Description
    SIGXFSZ ii File size limit execeeded


    ii Abnormal termination of the process.
    Additionally, implementation-dependent abnormal termination actions, such
    as creation of a core file, may occur."

    Under UNIX95, a process must set up a handler for SIGXFSZ or use
    sigignore(SIGXFSZ) and watch the return code and errno from the system
    call. This requirement is further re-enforced in base resolution request 1170/81.

    limit is reached, an I/O error or EOF condition occurred.

    CREATE child process
    CHILD:
    SET signal catching function so that the parent is informed that a
    signal has been caught

    whichever is greater
    OPEN stream readonly using fopen()
    SET stream to be unbuffered using setbuf()
    WRITE data to stream so that the file is almost full using fwrite()
    WRITE data to stream so that the maximum file size is exceeded
    INFORM parent of the return value of fwrite() using sendsync() -
    (genlib)
    SET flag to indicate that data has been sent to the parent
    CLOSE stream using fclose()
    PARENT:
    WAIT for child to complete processing using waitsync() - (genlib)
    DELETE the test case if the child process has taken too long
    VERIFY that the child process has successfully completed processing
    VERIFY that no errors occurred in the child process
    VERIFY that the expected number of items have been written to the file
    UNLINK data file

    Review Recommendation No Resolution Given
    Review Response
    The TET_SIG_IGN configuration parameter allows for signals to be ignored
    during the execution of a test suite and the SIGXFSZ signal should be
    included in the TET_SIG_IGN list when executing the VSX test suite. A note
    will be added to the VSX User Guide to clarify this.

    It is recommended that this request is refused and that the VSX user sets
    the configuration to ignore this signal, as recommended in the UNIX95
    specification.
