NAME

       smlistsh - shared-memory linked list test shell

SYNOPSIS

       smlistsh partition_size

DESCRIPTION

       smlistsh attaches to a region of system memory (allocating it if necessary, and placing it under PSM
       management as necessary) and offers the user an interactive "shell" for testing various shared-memory
       linked list management functions.

       smlistsh prints a prompt string (": ") to stdout, accepts a command from stdin, executes the command
       (possibly printing a diagnostic message), then prints another prompt string and so on.

       The following commands are supported:

       h   The help command.  Causes smlistsh to print a summary of available commands.  Same effect as the ?
           command.

       ?   Another help command.  Causes smlistsh to print a summary of available commands.  Same effect as the
           h command.

       k   The key command.  Computes and prints an unused shared-memory key, for possible use in attaching to a
           shared-memory region.

       + key_value size
           The attach command.  Attaches smlistsh to a region of shared memory.  key_value identifies an
           existing shared-memory region, in the event that you want to attach to an existing shared-memory
           region (possibly created by another smlistsh process running on the same computer).  To create and
           attach to a new shared-memory region that other processes can attach to, use a key_value as returned
           by the key command and supply the size of the new region.  If you want to create and attach to a new
           shared-memory region that is for strictly private use, use -1 as key and supply the size of the new
           region.

       -   The detach command.  Detaches smlistsh from the region of shared memory it is currently using, but
           does not free any memory.

       n   The new command.  Creates a new shared-memory list to operate on, within the currently attached
           shared-memory region.  Prints the address of the list.

       s list_address
           The share command.  Selects an existing shared-memory list to operate on, within the currently
           attached shared-memory region.

       a element_value
           The append command.  Appends a new list element, containing element_value, to the list on which
           smlistsh is currently operating.

       p element_value
           The prepend command.  Prepends a new list element, containing element_value, to the list on which
           smlistsh is currently operating.

       w   The walk command.  Prints the addresses and contents of all elements of the list on which smlistsh is
           currently operating.

       f element_value
           The find command.  Finds the list element that contains element_value, within the list on which
           smlistsh is currently operating, and prints the address of that list element.

       d element_address
           The delete command.  Deletes the list element located at element_address.

       r   The report command.  Prints a partition usage report, as per psm_report(3).

       q   The quit command.  Detaches smlistsh from the region of shared memory it is currently using (without
           freeing any memory) and terminates smlistsh.

EXIT STATUS

       "0" smlistsh has terminated.
