Obtain a sorted directory listing.
The prototype of sort_dir is a little scary, but it is easy to use. For example, to sort a given directory alphabetically:
char **list; int i;
sort_dir(dirname,&list,strcmp);
for(i=0;list[i];i++) printf("%s\n",list[i]);sort_dir_free(list);
| int sort_dir | ( | const char * | dirname, |
| char *** | list, | ||
| int(*)(const char *a, const char *b) | sort | ||
| ) |
Obtain a sorted directory listing.
| dirname | The directory to list. |
| list | A pointer to a doubly-indirect pointer, which will be filled with a list of strings. The final item will be null. This list must be freed with sort_dir_free. |
| sort | A pointer to a function to compare two strings, which must have the same semantics as strcmp |
| void sort_dir_free | ( | char ** | list | ) |
Free a sorted directory listing.
| list | The list to be freed. |
