sub_strings.i1p.r = str_split_by_char_set_c(source_string.i1a.r,

	This routine returns the array of substrings making up a larger
	string.  The delimiters between adjacent substrings is determined
	by a passed string.  This routine allocates the memory for the
	array of substrings.  This memory is freed on the next call to this
	routine in which a string is successfully split unless the option
	STR_OPT_NO_STATIC_MEMORY is selected.  In spite of this,
	you can still use a substring extracted by this call as the input
	string to the next call to this routine.

	source_string	string to be split
	source_length	length of string to be split  (If this argument
			has a value of zero, the routine will determine
			the length of the string.)
	delimiters	null terminated list of delimiter characters
	options		use options
			(STR_OPT_NONE -> no options selected,
			 STR_OPT_NO_TRIM -> don't trim spaces from substrings,
			 STR_OPT_HANDLE_QUOTES -> handle substrings which
						  are quoted strings,
			 STR_OPT_HANDLE_EMBEDDED_QUOTES -> handle substrings
							   which have quoted
							   strings embedded
							   in them,
			 STR_OPT_PRESERVE_QUOTES -> preserve the quote
						    characters in quoted
			 STR_OPT_HANDLE_BRACES -> handle substrings which
						  are bracketed strings,
			 STR_OPT_HANDLE_EMBEDDED_BRACES -> handle substrings
							   which have bracketed
							   strings embedded
							   in them,
			 STR_OPT_HANDLE_PARENTHESES -> handle substrings which
						       are parenthetical
								which have
								strings embedded
								in them,
			 STR_OPT_NO_STATIC_MEMORY -> don't utilize static memory
						     (caller must free string
						      memory preferably with
			 STR_OPT_RETURN_UNSPLIT_STRINGS -> return strings that
							   couldn't be split
							   (default is to return
							    a 0 for the number
							    of strings and an
							    overall value of

	num_substrings	returned number of substrings found
			(A value of NULL can be passed for this argument
			 if this information is not needed.)
	[actual_delims]	returned actual delimiters found
			(The memory for this argument is allocated by
			 this routine and should be freed by the caller.)
			(default is NULL)
	[max_splits]	maximum number of split characters to look for
			(default is 0 which results in searching for all splits)

	This function returns values as follows:

	NULL			delimiter string not found
	otherwise		array of pointers to substrings
