72 | ||
73 | /* Scan the spool directory and return a list of the relevant file names | |
74 | therein. Single-character sub-directories are handled as follows: | |
75 | ||
76 | If the first argument is > 0, a sub-directory is scanned; the letter is | |
77 | taken from the nth entry in subdirs. | |
78 | ||
79 | If the first argument is 0, sub-directories are not scanned. However, a | |
80 | list of them is returned. | |
81 | ||
82 | If the first argument is < 0, sub-directories are scanned for messages, | |
83 | and a single, unified list is created. The returned data blocks contain the | |
84 | identifying character of the subdirectory, if any. The subdirs vector is | |
85 | still required as an argument. | |
86 | ||
87 | If the randomize argument is TRUE, messages are returned in "randomized" order. | |
88 | Actually, the order is anything but random, but the algorithm is cheap, and the | |
89 | point is simply to ensure that the same order doesn't occur every time, in case | |
90 | a particular message is causing a remote MTA to barf - we would like to try | |
91 | other messages to that MTA first. | |
92 | ||
93 | If the randomize argument is FALSE, sort the list according to the file name. | |
94 | This should give the order in which the messages arrived. It is normally used | |
95 | only for presentation to humans, in which case the (possibly expensive) sort | |
96 | that it does is not part of the normal operational code. However, if | |
97 | queue_run_in_order is set, sorting has to take place for queue runs as well. | |
98 | When randomize is FALSE, the first argument is normally -1, so all messages are | |
99 | included. | |
100 | ||
101 | Arguments: | |
102 | subdiroffset sub-directory character offset, or 0 or -1 (see above) | |
103 | subdirs vector to store list of subdirchars | |
104 | subcount pointer to int in which to store count of subdirs | |
105 | randomize TRUE if the order of the list is to be unpredictable | |
106 | ||
