3878 * File searching functions for 'path', 'tags' and 'cdpath' options. | |
3879 * External visible functions: | |
3880 * vim_findfile_init() creates/initialises the search context | |
3881 * vim_findfile_free_visited() free list of visited files/dirs of search | |
3882 * context | |
3883 * vim_findfile() find a file in the search context | |
3884 * vim_findfile_cleanup() cleanup/free search context created by | |
3885 * vim_findfile_init() | |
3886 * | |
3887 * All static functions and variables start with 'ff_' | |
3888 * | |
3889 * In general it works like this: | |
3890 * First you create yourself a search context by calling vim_findfile_init(). | |
3891 * It is possible to give a search context from a previous call to | |
3892 * vim_findfile_init(), so it can be reused. After this you call vim_findfile() | |
3893 * until you are satisfied with the result or it returns NULL. On every call it | |
3894 * returns the next file which matches the conditions given to | |
3895 * vim_findfile_init(). If it doesn't find a next file it returns NULL. | |
3896 * | |
3897 * It is possible to call vim_findfile_init() again to reinitialise your search | |
3898 * with some new parameters. Don't forget to pass your old search context to | |
3899 * it, so it can reuse it and especially reuse the list of already visited | |
3900 * directories. If you want to delete the list of already visited directories | |
3901 * simply call vim_findfile_free_visited(). | |
3902 * | |
3903 * When you are done call vim_findfile_cleanup() to free the search context. | |
3904 * | |
3905 * The function vim_findfile_init() has a long comment, which describes the | |
3906 * needed parameters. | |
3907 * | |
3908 * | |
3909 * | |
3910 * ATTENTION: | |
3911 * ========== | |
1072 | 3912 * Also we use an allocated search context here, this functions are NOT |
7 | 3913 * thread-safe!!!!! |
3914 * | |
3915 * To minimize parameter passing (or because I'm to lazy), only the | |
3916 * external visible functions get a search context as a parameter. This is | |
3917 * then assigned to a static global, which is used throughout the local | |
3918 * functions. | |

4136 * If the 'path' is absolute, the starting dir is that part of the path before |
7 | 4137 * the first wildcard. |
4138 * | |
4139 * Upward search is only done on the starting dir. | |
4140 * | |
4141 * If 'free_visited' is TRUE the list of already visited files/directories is | |
4142 * cleared. Set this to FALSE if you just want to search from another | |
4143 * directory, but want to be sure that no directory from a previous search is | |
4144 * searched again. This is useful if you search for a file at different places. | |
4145 * The list of visited files/dirs can also be cleared with the function | |
4146 * vim_findfile_free_visited(). | |
4147 * | |
1541 | 4148 * Set the parameter 'find_what' to FINDFILE_DIR if you want to search for |
4149 * directories only, FINDFILE_FILE for files only, FINDFILE_BOTH for both. | |
7 | 4150 * |
4151 * A search context returned by a previous call to vim_findfile_init() can be | |
1541 | 4152 * passed in the parameter "search_ctx_arg". This context is reused and |
4153 * reinitialized with the new parameters. The list of already visited | |
7 | 4154 * directories from this context is only deleted if the parameter |
1541 | 4155 * "free_visited" is true. Be aware that the passed "search_ctx_arg" is freed |
4156 * if the reinitialization fails. | |
7 | 4157 * |
1541 | 4158 * If you don't have a search context from a previous call "search_ctx_arg" |
4159 * must be NULL. | |
7 | 4160 * |
4161 * This function silently ignores a few errors, vim_findfile() will have | |
4162 * limited functionality then. | |
