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