dudmuck 336:1e18a06a987b 54 *
dudmuck 336:1e18a06a987b 55 * This allows programs to read and write files on the same disk drive that is used to program the
dudmuck 336:1e18a06a987b 56 * mbed Microcontroller. Once created, the standard C file access functions are used to open,
dudmuck 336:1e18a06a987b 57 * read and write files.
dudmuck 336:1e18a06a987b 58 *
dudmuck 336:1e18a06a987b 59 * Example:
dudmuck 336:1e18a06a987b 60 * @code
dudmuck 336:1e18a06a987b 61 * #include "mbed.h"
dudmuck 336:1e18a06a987b 62 *
dudmuck 336:1e18a06a987b 63 * LocalFileSystem local("local"); // Create the local filesystem under the name "local"
dudmuck 336:1e18a06a987b 64 *
dudmuck 336:1e18a06a987b 65 * int main() {
dudmuck 336:1e18a06a987b 66 * FILE *fp = fopen("/local/out.txt", "w"); // Open "out.txt" on the local file system for writing
dudmuck 336:1e18a06a987b 67 * fprintf(fp, "Hello World!");
dudmuck 336:1e18a06a987b 68 * fclose(fp);
dudmuck 336:1e18a06a987b 69 * remove("/local/out.txt"); // Removes the file "out.txt" from the local file system
dudmuck 336:1e18a06a987b 70 *
dudmuck 336:1e18a06a987b 71 * DIR *d = opendir("/local"); // Opens the root directory of the local file system
dudmuck 336:1e18a06a987b 72 * struct dirent *p;
dudmuck 336:1e18a06a987b 73 * while((p = readdir(d)) != NULL) { // Print the names of the files in the local file system
dudmuck 336:1e18a06a987b 74 * printf("%s\n", p->d_name); // to stdout.

dudmuck 336:1e18a06a987b 76 * closedir(d);
dudmuck 336:1e18a06a987b 77 * }
dudmuck 336:1e18a06a987b 78 * @endcode
dudmuck 336:1e18a06a987b 79 *
dudmuck 336:1e18a06a987b 80 * @note
dudmuck 336:1e18a06a987b 81 * If the microcontroller program makes an access to the local drive, it will be marked as "removed"
dudmuck 336:1e18a06a987b 82 * on the Host computer. This means it is no longer accessible from the Host Computer.
dudmuck 336:1e18a06a987b 83 *
dudmuck 336:1e18a06a987b 84 * The drive will only re-appear when the microcontroller program exists. Note that if the program does
dudmuck 336:1e18a06a987b 85 * not exit, you will need to hold down reset on the mbed Microcontroller to be able to see the drive again!
