| 4116 * File searching functions for 'path', 'tags' and 'cdpath' options. | |
| 4117 * External visible functions: | |
| 4118 * vim_findfile_init() creates/initialises the search context | |
| 4119 * vim_findfile_free_visited() free list of visited files/dirs of search | |
| 4120 * context | |
| 4121 * vim_findfile() find a file in the search context | |
| 4122 * vim_findfile_cleanup() cleanup/free search context created by | |
| 4123 * vim_findfile_init() | |
| 4124 * | |
| 4125 * All static functions and variables start with 'ff_' | |
| 4126 * | |
| 4127 * In general it works like this: | |
| 4128 * First you create yourself a search context by calling vim_findfile_init(). | |
| 4129 * It is possible to give a search context from a previous call to | |
| 4130 * vim_findfile_init(), so it can be reused. After this you call vim_findfile() | |
| 4131 * until you are satisfied with the result or it returns NULL. On every call it | |
| 4132 * returns the next file which matches the conditions given to | |
| 4133 * vim_findfile_init(). If it doesn't find a next file it returns NULL. | |
| 4134 * | |
| 4135 * It is possible to call vim_findfile_init() again to reinitialise your search | |
| 4136 * with some new parameters. Don't forget to pass your old search context to | |
| 4137 * it, so it can reuse it and especially reuse the list of already visited | |
| 4138 * directories. If you want to delete the list of already visited directories | |
| 4139 * simply call vim_findfile_free_visited(). | |
| 4140 * | |
| 4141 * When you are done call vim_findfile_cleanup() to free the search context. | |
| 4142 * | |
| 4143 * The function vim_findfile_init() has a long comment, which describes the | |
| 4144 * needed parameters. | |
| 4145 * | |
| 4146 * | |
| 4147 * | |
| 4148 * ATTENTION: | |

| 1072 | 4150 * Also we use an allocated search context here, this functions are NOT |
| 7 | 4151 * thread-safe!!!!! |
| 4152 * | |
| 4153 * To minimize parameter passing (or because I'm to lazy), only the | |
| 4154 * external visible functions get a search context as a parameter. This is | |
| 4155 * then assigned to a static global, which is used throughout the local | |
| 4156 * functions. | |
