-DESCRIPTION:
-Parse the command line for specific options
-
-HEADER:
-cmdline.h
-
-PARAMETERS:
-argc        - Value passed to program through argc variable
-argv        - Pointer to the argv array passed to the program
-format      - A string representing the expected format of the command line
-argument    - Pointer to optional argument on command line
-
-RETURNS:
-Character code representing the next option parsed from the command line by
-getcmdopt. Returns ALLDONE (-1) when there are no more parameters to be parsed
-on the command line, PARAMETER (-2) when the argument being parsed is a
-parameter and not an option switch and lastly INVALID (-3) if an error
-occured while parsing the command line.
-
-REMARKS:
-Function to parse the command line option switches in UNIX System V style.
-When getcmdopt is called, it returns the character code of the next valid
-option that is parsed from the command line as specified by the Format
-string. The format string should be in the following form:
-
-    "abcd:e:f:"
-
-where a,b and c represent single switch style options and the character
-code returned by getcmdopt is the only value returned. Also d, e and f
-represent options that expect arguments immediately after them on the
-command line. The argument that follows the option on the command line is
-returned via a reference in the pointer argument. Thus a valid command line
-for this format string might be:
-
-    myprogram -adlines -b -f format infile outfile
-
-where a and b will be returned as single character options with no argument,
-while d is returned with the argument lines and f is returned with the
-argument format.
-
-When getcmdopt returns with PARAMETER (we attempted to parse a paramter, not
-an option), the global variable NextArgv will hold an index in the argv
-array to the argument on the command line AFTER the options, ie in the
-above example the string 'infile'. If the parameter is successfully used,
-NextArgv should be incremented and getcmdopt can be called again to parse any
-more options. Thus you can also have options interspersed throught the
-command line. eg:
-
-    myprogram -adlines infile -b outfile -f format
-
-can be made to be a valid form of the above command line.

-PARAMETERS:
-argc        - Number of arguments on command line
-argv        - Array of command line arguments

-RETURNS:
-ALLDONE, INVALID or HELP
-
-REMARKS:
-Function to parse the command line according to a table of options. This
-routine calls getcmdopt above to parse each individual option and attempts
-to parse each option into a variable of the specified type. The routine
-can parse integers and long integers in either decimal, octal, hexadecimal
-notation, unsigned integers and unsigned longs, strings and option switches.
-Option switches are simply boolean variables that get turned on if the
-switch was parsed.
-
-Parameters are extracted from the command line by calling a user supplied
-routine do_param() to handle each parameter as it is encountered. The
-routine do_param() should accept a pointer to the parameter on the command
-line and an integer representing how many parameters have been encountered
-(ie: 1 if this is the first parameter, 10 if it is the 10th etc), and return
-ALLDONE upon successfully parsing it or INVALID if the parameter was invalid.
-
-We return either ALLDONE if all the options were successfully parsed,
-INVALID if an invalid option was encountered or HELP if any of -h, -H or
--? were present on the command line.
