VMS Help System Services, $START ALIGN FAULT REPORT (Alpha Only)  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    On Alpha systems, initializes user image alignment fault
    reporting.

    Format

      SYS$START_ALIGN_FAULT_REPORT  report_method ,report_buffer

                                    ,buffer_length

    C Prototype

      int sys$start_align_fault_report  (int report_method,

                                        void *report_buffer, int

                                        buffer_length);

1 - Arguments

 report_method

    OpenVMS usage:longword_signed
    type:         longword (signed)
    access:       read
    mechanism:    by value
    Method by which image alignment faults are to be reported.

    The following table shows valid values for the report_method
    argument:

    Value          Meaning

    AFR$C_         Alignment fault PCs and fault addresses are saved
    BUFFERED       in a user-supplied buffer.
    AFR$C_         Alignment faults are elevated to user mode
    EXCEPTION      exceptions.

 report_buffer

    OpenVMS usage:address
    type:         longword (unsigned)
    access:       read
    mechanism:    by reference
    The 32-bit address of the buffer into which to write the fault
    data. The report_buffer argument is needed only if the value of
    the report_method argument is AFR$C_BUFFERED.

 buffer_length

    OpenVMS usage:byte count
    type:         longword (signed)
    access:       read
    mechanism:    by value
    Length of the buffer specified in the report_buffer argument.

    The buffer must have a minimum size of AFR$K_USER_LENGTH +
    32. However, a larger buffer allows for more information to be
    collected.
