NAME

       VistaIOReportUsage, VistaIOReportValidOptions - report valid command line arguments

SYNOPSIS

       #include <vistaio.h>

       void VistaIOReportUsage (program, noptions, options, other_args)
              VistaIOStringConst program, other_args;
              int noptions;
              VistaIOOptionDescRec options[noptions];

       void VistaIOReportValidOptions (noptions, options)
              int noptions;
              VistaIOOptionDescRec options[noptions];

ARGUMENTS

       program   Specifies the program's name. Usually argv[0] is passed.

       noptions  Specifies the number of entries in the table of option descriptors.

       options   Specifies the location of the table of option descriptors.

       other_args
                 May specify a string describing any options the program accepts other than those
                 described in the options table, or it may be NULL

DESCRIPTION

       VistaIOReportUsage prints, to the standard error stream, information about how  to  use  a
       program. It first prints a line of the form:

              Usage: program <options> other_args, where <options> includes:

       The  program  argument  supplies  the  program  component of this line, and the other_args
       argument supplies the other_args component. If the program accepts no options  other  than
       those described in the options table, other_args should be NULL.

       VistaIOReportUsage  then calls VistaIOReportValidOptions to print a summary of the options
       described by noptions and options.

       VistaIOReportValidOptions prints a description  of  each  option  in  a  table  of  option
       descriptors.  The  description  is  intended  to advise a program user.  It indicates what
       keyword signals the option's presence in the command line, whether  it  is  optional,  how
       many  values must follow it, what type those values should have, what keywords may be used
       as values for the option, and what default value(s) the option has.  The description  will
       also  include any ``blurb'' string of help information that is found in the option's table
       entry. The information is printed to the standard error stream.
