Added link to documentation and how to open a directory. |
||
Line 44:
You can also install it to /usr/local, to avoid having to do that.
===
Once the project is built, and your build system has the information to use the library, you can start writing code.
Line 95:
}
}
=== Opening a File ===
With the disk and the file system initialized, you can open the file.
int
/* Initialize disk here. */
Line 118 ⟶ 120:
}
bmfs_file_set_mode(&file,
char buf[512];
/* Read from or write to the file here. */▼
while (bmfs_file_eof(&file)) {
bmfs_uint64 read_count = 0;
err = bmfs_file_read(&file, buf, 512, &read_count);
if (err != 0)
break;
my_print_function(buf, read_count);
}
}
=== Opening a Directory ===
Opening a directory is similar to opening a file.
You'll have to initialize the file system the same as you did for the file.
int list_dir(const char *path) {
struct BMFSDir dir;
bmfs_dir_init(&dir);
int err = bmfs_open_dir(&bmfs, &dir, path);
if (err == ENOTDIR) {
kprintf("Entry '%s' is not a directory.\n", path);
return -1;
} else if (err == ENOENT) {
kprintf("Directory '%s' does not exist.\n", path);
return -1;
} else if (err != 0) {
kprintf("Failed to open directory '%s'.\n", path);
return -1;
}
for (;;) {
const struct BMFSEntry *entry = bmfs_dir_next(&dir);
if (entry == BMFS_NULL)
break;
kprintf("Entry: %s\n", entry->Name);
}
}
=== Going Further ===
The library can do even more than that and new features are added continuously.
Visit the Doxygen generated documentation [https://returninfinity.github.io/bmfs-doc/modules.html] for more information.
