jwhammel 84:fc8c9b39723a 54 *
jwhammel 84:fc8c9b39723a 55 * This allows programs to read and write files on the same disk drive that is used to program the
jwhammel 84:fc8c9b39723a 56 * mbed Microcontroller. Once created, the standard C file access functions are used to open,
jwhammel 84:fc8c9b39723a 57 * read and write files.
jwhammel 84:fc8c9b39723a 58 *
jwhammel 84:fc8c9b39723a 59 * Example:
jwhammel 84:fc8c9b39723a 60 * @code
jwhammel 84:fc8c9b39723a 61 * #include "mbed.h"
jwhammel 84:fc8c9b39723a 62 *
jwhammel 84:fc8c9b39723a 63 * LocalFileSystem local("local"); // Create the local filesystem under the name "local"
jwhammel 84:fc8c9b39723a 64 *
jwhammel 84:fc8c9b39723a 65 * int main() {
jwhammel 84:fc8c9b39723a 66 * FILE *fp = fopen("/local/out.txt", "w"); // Open "out.txt" on the local file system for writing
jwhammel 84:fc8c9b39723a 67 * fprintf(fp, "Hello World!");
jwhammel 84:fc8c9b39723a 68 * fclose(fp);
jwhammel 84:fc8c9b39723a 69 * remove("/local/out.txt"); // Removes the file "out.txt" from the local file system
jwhammel 84:fc8c9b39723a 70 *
jwhammel 84:fc8c9b39723a 71 * DIR *d = opendir("/local"); // Opens the root directory of the local file system
jwhammel 84:fc8c9b39723a 72 * struct dirent *p;
jwhammel 84:fc8c9b39723a 73 * while((p = readdir(d)) != NULL) { // Print the names of the files in the local file system
jwhammel 84:fc8c9b39723a 74 * printf("%s\n", p->d_name); // to stdout.
jwhammel 84:fc8c9b39723a 75 * }
jwhammel 84:fc8c9b39723a 76 * closedir(d);
jwhammel 84:fc8c9b39723a 77 * }
jwhammel 84:fc8c9b39723a 78 * @endcode
jwhammel 84:fc8c9b39723a 79 *
jwhammel 84:fc8c9b39723a 80 * @note
jwhammel 84:fc8c9b39723a 81 * If the microcontroller program makes an access to the local drive, it will be marked as "removed"
jwhammel 84:fc8c9b39723a 82 * on the Host computer. This means it is no longer accessible from the Host Computer.
jwhammel 84:fc8c9b39723a 83 *
jwhammel 84:fc8c9b39723a 84 * The drive will only re-appear when the microcontroller program exists. Note that if the program does
jwhammel 84:fc8c9b39723a 85 * not exit, you will need to hold down reset on the mbed Microcontroller to be able to see the drive again!
