gmatarrubia 0:820a69dfd200 53 /** A filesystem for accessing the local mbed Microcontroller USB disk drive
gmatarrubia 0:820a69dfd200 54 *
gmatarrubia 0:820a69dfd200 55 * This allows programs to read and write files on the same disk drive that is used to program the
gmatarrubia 0:820a69dfd200 56 * mbed Microcontroller. Once created, the standard C file access functions are used to open,
gmatarrubia 0:820a69dfd200 57 * read and write files.
gmatarrubia 0:820a69dfd200 58 *
gmatarrubia 0:820a69dfd200 59 * Example:
gmatarrubia 0:820a69dfd200 60 * @code
gmatarrubia 0:820a69dfd200 61 * #include "mbed.h"
gmatarrubia 0:820a69dfd200 62 *
gmatarrubia 0:820a69dfd200 63 * LocalFileSystem local("local"); // Create the local filesystem under the name "local"
gmatarrubia 0:820a69dfd200 64 *
gmatarrubia 0:820a69dfd200 65 * int main() {
gmatarrubia 0:820a69dfd200 66 * FILE *fp = fopen("/local/out.txt", "w"); // Open "out.txt" on the local file system for writing
gmatarrubia 0:820a69dfd200 67 * fprintf(fp, "Hello World!");
gmatarrubia 0:820a69dfd200 68 * fclose(fp);
gmatarrubia 0:820a69dfd200 69 * remove("/local/out.txt"); // Removes the file "out.txt" from the local file system
gmatarrubia 0:820a69dfd200 70 *
gmatarrubia 0:820a69dfd200 71 * DIR *d = opendir("/local"); // Opens the root directory of the local file system
gmatarrubia 0:820a69dfd200 72 * struct dirent *p;
gmatarrubia 0:820a69dfd200 73 * while((p = readdir(d)) != NULL) { // Print the names of the files in the local file system
gmatarrubia 0:820a69dfd200 74 * printf("%s\n", p->d_name); // to stdout.
gmatarrubia 0:820a69dfd200 75 * }
gmatarrubia 0:820a69dfd200 76 * closedir(d);
gmatarrubia 0:820a69dfd200 77 * }
gmatarrubia 0:820a69dfd200 78 * @endcode
gmatarrubia 0:820a69dfd200 79 *
gmatarrubia 0:820a69dfd200 80 * @note
gmatarrubia 0:820a69dfd200 81 * If the microcontroller program makes an access to the local drive, it will be marked as "removed"
gmatarrubia 0:820a69dfd200 82 * on the Host computer. This means it is no longer accessible from the Host Computer.
gmatarrubia 0:820a69dfd200 83 *
gmatarrubia 0:820a69dfd200 84 * The drive will only re-appear when the microcontroller program exists. Note that if the program does
gmatarrubia 0:820a69dfd200 85 * not exit, you will need to hold down reset on the mbed Microcontroller to be able to see the drive again!
