90 ** MAP.C -- implementations for various map classes.
92 ** Each map class implements a series of functions:
94 ** bool map_parse(MAP *map, char *args)
95 ** Parse the arguments from the config file. Return true
96 ** if they were ok, false otherwise. Fill in map with the
99 ** char *map_lookup(MAP *map, char *key, char **args, int *pstat)
100 ** Look up the key in the given map. If found, do any
101 ** rewriting the map wants (including "args" if desired)
102 ** and return the value. Set *pstat to the appropriate status
103 ** on error and return NULL. Args will be NULL if called
104 ** from the alias routines, although this should probably
105 ** not be relied upon. It is suggested you call map_rewrite
106 ** to return the results -- it takes care of null termination
107 ** and uses a dynamically expanded buffer as needed.
109 ** void map_store(MAP *map, char *key, char *value)
110 ** Store the key:value pair in the map.
112 ** bool map_open(MAP *map, int mode)
113 ** Open the map for the indicated mode. Mode should
114 ** be either O_RDONLY or O_RDWR. Return true if it
115 ** was opened successfully, false otherwise. If the open
116 ** failed and the MF_OPTIONAL flag is not set, it should
117 ** also print an error. If the MF_ALIAS bit is set
118 ** and this map class understands the @:@ convention, it
119 ** should call aliaswait() before returning.
121 ** void map_close(MAP *map)
124 ** This file also includes the implementation for getcanonname.
125 ** It is currently implemented in a pretty ad-hoc manner; it ought
126 ** to be more properly integrated into the map structure.
