slowness 0:c03cffe402df 38 /* Class: LocalFileSystem
slowness 0:c03cffe402df 39 * A filesystem for accessing the local mbed Microcontroller USB disk drive
slowness 0:c03cffe402df 40 *
slowness 0:c03cffe402df 41 * This allows programs to read and write files on the same disk drive that is used to program the
slowness 0:c03cffe402df 42 * mbed Microcontroller. Once created, the standard C file access functions are used to open,
slowness 0:c03cffe402df 43 * read and write files.
slowness 0:c03cffe402df 44 *
slowness 0:c03cffe402df 45 * Example:
slowness 0:c03cffe402df 46 * > #include "mbed.h"
slowness 0:c03cffe402df 47 * >
slowness 0:c03cffe402df 48 * > LocalFileSystem local("local"); // Create the local filesystem under the name "local"
slowness 0:c03cffe402df 49 * >
slowness 0:c03cffe402df 50 * > int main() {
slowness 0:c03cffe402df 51 * > FILE *fp = fopen("/local/out.txt", "w"); // Open "out.txt" on the local file system for writing
slowness 0:c03cffe402df 52 * > fprintf(fp, "Hello World!");
slowness 0:c03cffe402df 53 * > fclose(fp);
slowness 0:c03cffe402df 54 * > remove("/local/out.txt"); // Removes the file "out.txt" from the local file system
slowness 0:c03cffe402df 55 * >
slowness 0:c03cffe402df 56 * > DIR *d = opendir("/local"); // Opens the root directory of the local file system
slowness 0:c03cffe402df 57 * > struct dirent *p;
slowness 0:c03cffe402df 58 * > while((p = readdir(d)) != NULL) { // Print the names of the files in the local file system
slowness 0:c03cffe402df 59 * > printf("%s\n", p->d_name); // to stdout.
slowness 0:c03cffe402df 60 * > }
slowness 0:c03cffe402df 61 * > closedir(d);
slowness 0:c03cffe402df 62 * > }
slowness 0:c03cffe402df 63 *
slowness 0:c03cffe402df 64 * Implementation Notes:
slowness 0:c03cffe402df 65 * If the microcontroller program makes an access to the local drive, it will be marked as "removed"
slowness 0:c03cffe402df 66 * on the Host computer. This means it is no longer accessible from the Host Computer.
slowness 0:c03cffe402df 67 *
slowness 0:c03cffe402df 68 * The drive will only re-appear when the microcontroller program exists. Note that if the program does
slowness 0:c03cffe402df 69 * not exit, you will need to hold down reset on the mbed Microcontroller to be able to see the drive again!
