* PUBLIC DEFINES
*
* The following defines may be used in applications that need to test the
* state of an option. To test against these masks and values, a pointer
* to an option descriptor must be obtained. There are two ways:
*
* 1. inside an option processing procedure, it is the second argument,
* conventionally "tOptDesc* pOD".
*
* 2. Outside of an option procedure (or to reference a different option
* descriptor), use either "&DESC( opt_name )" or "&pfx_DESC( opt_name )".
*
* See the relevant generated header file to determine which and what
* values for "opt_name" are available.

*
* This function will convert one input string into a list of strings.
* The list of strings is derived by separating the input based on
* white space separation. However, if the input contains either single
* or double quote characters, then the text after that character up to
* a matching quote will become the string in the list.
*
* The returned pointer should be deallocated with @code{free(3C)} when
* are done using the data. The data are placed in a single block of
* allocated memory. Do not deallocate individual token/strings.
*
* The structure pointed to will contain at least these two fields:
* @table @samp
* @item tkn_ct
* The number of tokens found in the input string.
* @item tok_list
* An array of @code{tkn_ct + 1} pointers to substring tokens, with
* the last pointer set to NULL.
* @end table
*
* There are two types of quoted strings: single quoted (@code{'}) and
* double quoted (@code{"}). Singly quoted strings are fairly raw in that
* escape characters (@code{\\}) are simply another character, except when
* preceding the following characters:
* @example
* @code{\\} double backslashes reduce to one
* @code{'} incorporates the single quote into the string
* @code{\n} suppresses both the backslash and newline character
* @end example
