wyunreal 3:5dc0023e6284 13 /* Class: LocalFileSystem
wyunreal 3:5dc0023e6284 14 * A filesystem for accessing the local mbed Microcontroller USB disk drive
wyunreal 3:5dc0023e6284 15 *
wyunreal 3:5dc0023e6284 16 * This allows programs to read and write files on the same disk drive that is used to program the
wyunreal 3:5dc0023e6284 17 * mbed Microcontroller. Once created, the standard C file access functions are used to open,
wyunreal 3:5dc0023e6284 18 * read and write files.
wyunreal 3:5dc0023e6284 19 *
wyunreal 3:5dc0023e6284 20 * Example:
wyunreal 3:5dc0023e6284 21 * > #include "mbed.h"
wyunreal 3:5dc0023e6284 22 * >
wyunreal 3:5dc0023e6284 23 * > LocalFileSystem local("local"); // Create the local filesystem under the name "local"
wyunreal 3:5dc0023e6284 24 * >
wyunreal 3:5dc0023e6284 25 * > int main() {
wyunreal 3:5dc0023e6284 26 * > FILE *fp = fopen("/local/out.txt", "w"); // Open "out.txt" on the local file system for writing
wyunreal 3:5dc0023e6284 27 * > fprintf(fp, "Hello World!");
wyunreal 3:5dc0023e6284 28 * > fclose(fp);
wyunreal 3:5dc0023e6284 29 * > remove("/local/out.txt"); // Removes the file "out.txt" from the local file system
wyunreal 3:5dc0023e6284 30 * >
wyunreal 3:5dc0023e6284 31 * > DIR *d = opendir("/local"); // Opens the root directory of the local file system
wyunreal 3:5dc0023e6284 32 * > struct dirent *p;
wyunreal 3:5dc0023e6284 33 * > while((p = readdir(d)) != NULL) { // Print the names of the files in the local file system
wyunreal 3:5dc0023e6284 34 * > printf("%s\n", p->d_name); // to stdout.
wyunreal 3:5dc0023e6284 35 * > }
wyunreal 3:5dc0023e6284 36 * > closedir(d);
wyunreal 3:5dc0023e6284 37 * > }
wyunreal 3:5dc0023e6284 38 *
wyunreal 3:5dc0023e6284 39 * Implementation Notes:
wyunreal 3:5dc0023e6284 40 * If the microcontroller program makes an access to the local drive, it will be marked as "removed"
wyunreal 3:5dc0023e6284 41 * on the Host computer. This means it is no longer accessible from the Host Computer.
wyunreal 3:5dc0023e6284 42 *
wyunreal 3:5dc0023e6284 43 * The drive will only re-appear when the microcontroller program exists. Note that if the program does
wyunreal 3:5dc0023e6284 44 * not exit, you will need to hold down reset on the mbed Microcontroller to be able to see the drive again!
