Now has seperate header and list_entry * structures. Also added a large sprinking of assert()s to the list * code. * * Revision 1.6 2001/08/05 16:06:20 jongfoster * Modifiying "struct map" so that there are now separate header and * "map_entry" structures. This means that functions which modify a * map no longer need to return a pointer to the modified map. * Also, it no longer reverses the order of the entries (which may be * important with some advanced template substitutions). * * Revision 1.5 2001/07/29 18:43:08 jongfoster * Changing #ifdef _FILENAME_H to FILENAME_H_INCLUDED, to conform to * ANSI C rules. * * Revision 1.4 2001/06/29 13:30:37 oes * - Introduced enlist_unique_header() * - Removed logentry from cancelled commit * * Revision 1.3 2001/06/03 11:03:48 oes * introduced functions for new list type "map": map(), lookup(), * free_map(), and extended enlist_unique * * Revision 1.2 2001/06/01 18:49:17 jongfoster * Replaced "list_share" with "list" - the tiny memory gain was not * worth the extra complexity. * * Revision 1.1 2001/05/31 21:11:53 jongfoster * - Moved linked list support to new "list.c" file. * Structure definitions are still in project.h, * function prototypes are now in "list.h". * - Added support for "struct list_share", which is identical * to "struct list" except it saves memory by not duplicating * the strings. Obviously, this only works if there is some * other way of managing the memory used by the strings. * (These list_share lists are used for lists which last * for only 1 request, and where all the list entries are * just coming directly from entries in the actionsfile.) * Note that you still need to destroy list_share lists * properly to free the nodes - it's only the strings * which are shared. * * *********************************************************************/ #include "project.h" #ifdef __cplusplus extern "C" { #endif /* * struct list * * A linked list class. */ extern void init_list (struct list *the_list); extern void destroy_list (struct list *the_list); extern jb_err enlist (struct list *the_list, const char *str); extern jb_err enlist_unique (struct list *the_list, const char *str, size_t num_significant_chars); extern jb_err enlist_unique_header (struct list *the_list, const char *name, const char *value); extern jb_err enlist_first (struct list *the_list, const char *str); extern jb_err list_append_list_unique(struct list *dest, const struct list *src); extern jb_err list_duplicate (struct list *dest, const struct list *src); extern int list_remove_item(struct list *the_list, const char *str); extern int list_remove_list(struct list *dest, const struct list *src); extern void list_remove_all (struct list *the_list); extern int list_is_empty(const struct list *the_list); extern char * list_to_text(const struct list *the_list); /* * struct map * * A class which maps names to values. * * Note: You must allocate this through new_map() and free it * through free_map(). */ extern struct map * new_map (void); extern void free_map (struct map * the_map); extern jb_err map (struct map * the_map, const char * name, int name_needs_copying, const char * value, int value_needs_copying); extern jb_err unmap (struct map *the_map, const char *name); extern const char * lookup (const struct map * the_map, const char * name); /* Revision control strings from this header and associated .c file */ extern const char list_rcs[]; extern const char list_h_rcs[]; #ifdef __cplusplus } /* extern "C" */ #endif #endif /* ndef LIST_H_INCLUDED */ /* Local Variables: tab-width: 3 end: */
