7 * lists.h - the LIST structure and routines to manipulate them
9 * The whole of jam relies on lists of strings as a datatype. This
10 * module, in conjunction with newstr.c, handles these relatively
15 * LIST - list of strings
20 * list_append() - append a list onto another one, returning total
21 * list_new() - tack a string onto the end of a list of strings
22 * list_copy() - copy a whole list of strings
23 * list_sublist() - copy a subset of a list of strings
24 * list_free() - free a list of strings
25 * list_print() - print a list of strings to stdout
26 * list_printq() - print a list of safely quoted strings to a file
27 * list_length() - return the number of items in the list
29 * lol_init() - initialize a LOL (list of lists)
30 * lol_add() - append a LIST onto an LOL
31 * lol_free() - free the LOL and its LISTs
32 * lol_get() - return one of the LISTs in the LOL
33 * lol_print() - debug print LISTS separated by ":"
35 * 04/13/94 (seiwald) - added shorthand L0 for null list pointer
36 * 08/23/94 (seiwald) - new list_append()
37 * 10/22/02 (seiwald) - list_new() now does its own newstr()/copystr()
38 * 11/04/02 (seiwald) - const-ing for string literals
39 * 12/09/02 (seiwald) - new list_printq() for writing lists to Jambase
