mbed_official 0:fd0d7bdfcdc2 54 *
emilmont 2:143cac498751 55 * This allows programs to read and write files on the same disk drive that is used to program the
emilmont 2:143cac498751 56 * mbed Microcontroller. Once created, the standard C file access functions are used to open,
mbed_official 0:fd0d7bdfcdc2 57 * read and write files.
mbed_official 0:fd0d7bdfcdc2 58 *
mbed_official 0:fd0d7bdfcdc2 59 * Example:
mbed_official 0:fd0d7bdfcdc2 60 * @code
mbed_official 0:fd0d7bdfcdc2 61 * #include "mbed.h"
mbed_official 0:fd0d7bdfcdc2 62 *
mbed_official 0:fd0d7bdfcdc2 63 * LocalFileSystem local("local"); // Create the local filesystem under the name "local"
mbed_official 0:fd0d7bdfcdc2 64 *
mbed_official 0:fd0d7bdfcdc2 65 * int main() {
mbed_official 0:fd0d7bdfcdc2 66 * FILE *fp = fopen("/local/out.txt", "w"); // Open "out.txt" on the local file system for writing
emilmont 2:143cac498751 67 * fprintf(fp, "Hello World!");
emilmont 2:143cac498751 68 * fclose(fp);
mbed_official 0:fd0d7bdfcdc2 69 * remove("/local/out.txt"); // Removes the file "out.txt" from the local file system
mbed_official 0:fd0d7bdfcdc2 70 *
mbed_official 0:fd0d7bdfcdc2 71 * DIR *d = opendir("/local"); // Opens the root directory of the local file system
mbed_official 0:fd0d7bdfcdc2 72 * struct dirent *p;
mbed_official 0:fd0d7bdfcdc2 73 * while((p = readdir(d)) != NULL) { // Print the names of the files in the local file system
mbed_official 0:fd0d7bdfcdc2 74 * printf("%s\n", p->d_name); // to stdout.
mbed_official 0:fd0d7bdfcdc2 75 * }
mbed_official 0:fd0d7bdfcdc2 76 * closedir(d);
mbed_official 0:fd0d7bdfcdc2 77 * }
mbed_official 0:fd0d7bdfcdc2 78 * @endcode
mbed_official 0:fd0d7bdfcdc2 79 *
mbed_official 0:fd0d7bdfcdc2 80 * @note
mbed_official 0:fd0d7bdfcdc2 81 * If the microcontroller program makes an access to the local drive, it will be marked as "removed"
mbed_official 0:fd0d7bdfcdc2 82 * on the Host computer. This means it is no longer accessible from the Host Computer.
mbed_official 0:fd0d7bdfcdc2 83 *
mbed_official 0:fd0d7bdfcdc2 84 * The drive will only re-appear when the microcontroller program exists. Note that if the program does
mbed_official 0:fd0d7bdfcdc2 85 * not exit, you will need to hold down reset on the mbed Microcontroller to be able to see the drive again!
