bogdanm 13:0645d8841f51 53 /** A filesystem for accessing the local mbed Microcontroller USB disk drive
bogdanm 13:0645d8841f51 54 *
bogdanm 13:0645d8841f51 55 * This allows programs to read and write files on the same disk drive that is used to program the
bogdanm 13:0645d8841f51 56 * mbed Microcontroller. Once created, the standard C file access functions are used to open,
bogdanm 13:0645d8841f51 57 * read and write files.
bogdanm 13:0645d8841f51 58 *
bogdanm 13:0645d8841f51 59 * Example:
bogdanm 13:0645d8841f51 60 * @code
bogdanm 13:0645d8841f51 61 * #include "mbed.h"
bogdanm 13:0645d8841f51 62 *
bogdanm 13:0645d8841f51 63 * LocalFileSystem local("local"); // Create the local filesystem under the name "local"
bogdanm 13:0645d8841f51 64 *
bogdanm 13:0645d8841f51 65 * int main() {
bogdanm 13:0645d8841f51 66 * FILE *fp = fopen("/local/out.txt", "w"); // Open "out.txt" on the local file system for writing
bogdanm 13:0645d8841f51 67 * fprintf(fp, "Hello World!");
bogdanm 13:0645d8841f51 68 * fclose(fp);
bogdanm 13:0645d8841f51 69 * remove("/local/out.txt"); // Removes the file "out.txt" from the local file system
bogdanm 13:0645d8841f51 70 *
bogdanm 13:0645d8841f51 71 * DIR *d = opendir("/local"); // Opens the root directory of the local file system
bogdanm 13:0645d8841f51 72 * struct dirent *p;
bogdanm 13:0645d8841f51 73 * while((p = readdir(d)) != NULL) { // Print the names of the files in the local file system
bogdanm 13:0645d8841f51 74 * printf("%s\n", p->d_name); // to stdout.
bogdanm 13:0645d8841f51 75 * }
bogdanm 13:0645d8841f51 76 * closedir(d);
bogdanm 13:0645d8841f51 77 * }
bogdanm 13:0645d8841f51 78 * @endcode
bogdanm 13:0645d8841f51 79 *
bogdanm 13:0645d8841f51 80 * @note
bogdanm 13:0645d8841f51 81 * If the microcontroller program makes an access to the local drive, it will be marked as "removed"
bogdanm 13:0645d8841f51 82 * on the Host computer. This means it is no longer accessible from the Host Computer.
bogdanm 13:0645d8841f51 83 *
bogdanm 13:0645d8841f51 84 * The drive will only re-appear when the microcontroller program exists. Note that if the program does
bogdanm 13:0645d8841f51 85 * not exit, you will need to hold down reset on the mbed Microcontroller to be able to see the drive again!
