skrawool 0:3954a906acc2 60 *
skrawool 0:3954a906acc2 61 * This allows programs to read and write files on the same disk drive that is used to program the
skrawool 0:3954a906acc2 62 * mbed Microcontroller. Once created, the standard C file access functions are used to open,
skrawool 0:3954a906acc2 63 * read and write files.

skrawool 0:3954a906acc2 65 * @Note Synchronization level: Thread safe
skrawool 0:3954a906acc2 66 *
skrawool 0:3954a906acc2 67 * Example:
skrawool 0:3954a906acc2 68 * @code
skrawool 0:3954a906acc2 69 * #include "mbed.h"
skrawool 0:3954a906acc2 70 *
skrawool 0:3954a906acc2 71 * LocalFileSystem local("local"); // Create the local filesystem under the name "local"
skrawool 0:3954a906acc2 72 *
skrawool 0:3954a906acc2 73 * int main() {

skrawool 0:3954a906acc2 75 * fprintf(fp, "Hello World!");
skrawool 0:3954a906acc2 76 * fclose(fp);
skrawool 0:3954a906acc2 77 * remove("/local/out.txt"); // Removes the file "out.txt" from the local file system

skrawool 0:3954a906acc2 87 *
skrawool 0:3954a906acc2 88 * @note
skrawool 0:3954a906acc2 89 * If the microcontroller program makes an access to the local drive, it will be marked as "removed"
skrawool 0:3954a906acc2 90 * on the Host computer. This means it is no longer accessible from the Host Computer.
skrawool 0:3954a906acc2 91 *
skrawool 0:3954a906acc2 92 * The drive will only re-appear when the microcontroller program exists. Note that if the program does
skrawool 0:3954a906acc2 93 * not exit, you will need to hold down reset on the mbed Microcontroller to be able to see the drive again!
