annotate src/misc2.c @ 2768:c5e47b752f07 v7.3.160

of strcat().

| 4044 * vim_findfile() find a file in the search context | |
| 4045 * vim_findfile_cleanup() cleanup/free search context created by | |
| 4046 * vim_findfile_init() | |
| 4047 * | |
| 4048 * All static functions and variables start with 'ff_' | |
| 4049 * | |
| 4050 * In general it works like this: | |
| 4051 * First you create yourself a search context by calling vim_findfile_init(). | |
| 4052 * It is possible to give a search context from a previous call to | |
| 4053 * vim_findfile_init(), so it can be reused. After this you call vim_findfile() | |
| 4054 * until you are satisfied with the result or it returns NULL. On every call it | |
| 4055 * returns the next file which matches the conditions given to | |
| 4056 * vim_findfile_init(). If it doesn't find a next file it returns NULL. | |
| 4057 * | |
| 4058 * It is possible to call vim_findfile_init() again to reinitialise your search | |
| 4059 * with some new parameters. Don't forget to pass your old search context to | |
| 4060 * it, so it can reuse it and especially reuse the list of already visited | |
| 4061 * directories. If you want to delete the list of already visited directories | |
| 4062 * simply call vim_findfile_free_visited(). | |
| 4063 * | |
| 4064 * When you are done call vim_findfile_cleanup() to free the search context. | |
| 4065 * | |
| 4066 * The function vim_findfile_init() has a long comment, which describes the | |
| 4067 * needed parameters. | |
| 4068 * | |
| 4069 * | |
| 4070 * | |
| 4071 * ATTENTION: | |
| 4072 * ========== | |
| 1072 | 4073 * Also we use an allocated search context here, this functions are NOT |
| 7 | 4074 * thread-safe!!!!! |
| 4075 * | |
| 4076 * To minimize parameter passing (or because I'm to lazy), only the | |
| 4077 * external visible functions get a search context as a parameter. This is | |
| 4078 * then assigned to a static global, which is used throughout the local | |
| 4079 * functions. | |
