***=== INTRODUCTION =========================================================
|
|
|
38 |
*
|
|
|
39 |
* This file specifies the interface to a string list facility. This
|
|
|
40 |
* particular facility allows lists of nstrings (defined in the files
|
|
|
41 |
* "dstring.[ch]") to be created.
|
|
|
42 |
*
|
|
|
43 |
***=== TYPES ================================================================
|
|
|
44 |
*
|
|
|
45 |
** Type: NStringListEntryT
|
|
|
46 |
** Type: NStringListEntryP
|
|
|
47 |
** Repr: <private>
|
|
|
48 |
*
|
|
|
49 |
* This is the nstring list entry type.
|
|
|
50 |
*
|
|
|
51 |
** Type: NStringListT
|
|
|
52 |
** Type: NStringListP
|
|
|
53 |
** Repr: <private>
|
|
|
54 |
*
|
|
|
55 |
* This is the nstring list type.
|
|
|
56 |
*
|
|
|
57 |
***=== FUNCTIONS ============================================================
|
|
|
58 |
*
|
|
|
59 |
** Function: void nstring_list_init
|
|
|
60 |
* PROTO_S ((NStringListP list))
|
|
|
61 |
** Exceptions:
|
|
|
62 |
*
|
|
|
63 |
* This function initialises the specified nstring list to be an empty list.
|
|
|
64 |
*
|
|
|
65 |
** Function: void nstring_list_append
|
|
|
66 |
* PROTO_S ((NStringListP list, NStringP nstring))
|
|
|
67 |
** Exceptions: XX_dalloc_no_memory
|
|
|
68 |
*
|
|
|
69 |
* This function appends the specified nstring onto the specified list.
|
|
|
70 |
*
|
|
|
71 |
** Function: NStringListEntryP nstring_list_head
|
|
|
72 |
* PROTO_S ((NStringListP list))
|
|
|
73 |
** Exceptions:
|
|
|
74 |
*
|
|
|
75 |
* This function returns a pointer to the first entry in the specified list.
|
|
|
76 |
*
|
|
|
77 |
** Function: NStringP nstring_list_entry_string
|
|
|
78 |
* PROTO_S ((NStringListEntryP entry))
|
|
|
79 |
** Exceptions:
|
|
|
80 |
*
|
|
|
81 |
* This function returns a pointer to the nstring stored in the specified
|
|
|
82 |
* list entry.
|
|
|
83 |
*
|
|
|
84 |
** Function: NStringListEntryP nstring_list_entry_deallocate
|
|
|
85 |
* PROTO_S ((NStringListEntryP entry))
|
|
|
86 |
** Exceptions:
|
|
|
87 |
*
|
|
|
88 |
* This function deallocates the specified list entry (without deallocating
|
|
|
89 |
* the string - this must be done by the calling function) and returns a
|
|
|
90 |
* pointer to the next entry in the list. Once this function has been called,
|
|
|
91 |
* the state of the list that the entry is a member of is undefined. It is
|
|
|
92 |
* only useful for deallocating the entire list in a loop.
|
|
|
93 |
