107 | /* Scan the spool directory and return a list of the relevant file names | |
108 | therein. Single-character sub-directories are handled as follows: | |
109 | ||
110 | If the first argument is > 0, a sub-directory is scanned; the letter is | |
111 | taken from the nth entry in subdirs. | |
112 | ||
113 | If the first argument is 0, sub-directories are not scanned. However, a | |
114 | list of them is returned. | |
115 | ||
116 | If the first argument is < 0, sub-directories are scanned for messages, | |
117 | and a single, unified list is created. The returned data blocks contain the | |
118 | identifying character of the subdirectory, if any. The subdirs vector is | |
119 | still required as an argument. | |
120 | ||
121 | If the randomize argument is TRUE, messages are returned in "randomized" order. | |
122 | Actually, the order is anything but random, but the algorithm is cheap, and the | |
123 | point is simply to ensure that the same order doesn't occur every time, in case | |
124 | a particular message is causing a remote MTA to barf - we would like to try | |
125 | other messages to that MTA first. | |
126 | ||
127 | If the randomize argument is FALSE, sort the list according to the file name. | |
128 | This should give the order in which the messages arrived. It is normally used | |
129 | only for presentation to humans, in which case the (possibly expensive) sort | |
130 | that it does is not part of the normal operational code. However, if | |
131 | queue_run_in_order is set, sorting has to take place for queue runs as well. | |
132 | When randomize is FALSE, the first argument is normally -1, so all messages are | |
133 | included. | |
134 | ||
135 | Arguments: | |
136 | subdiroffset sub-directory character offset, or 0 or -1 (see above) | |
137 | subdirs vector to store list of subdirchars | |
138 | subcount pointer to int in which to store count of subdirs | |
139 | randomize TRUE if the order of the list is to be unpredictable | |
