yihui 5:b8c02645e6af 54 *
yihui 5:b8c02645e6af 55 * This allows programs to read and write files on the same disk drive that is used to program the
yihui 5:b8c02645e6af 56 * mbed Microcontroller. Once created, the standard C file access functions are used to open,
yihui 5:b8c02645e6af 57 * read and write files.
yihui 5:b8c02645e6af 58 *
yihui 5:b8c02645e6af 59 * Example:
yihui 5:b8c02645e6af 60 * @code
yihui 5:b8c02645e6af 61 * #include "mbed.h"
yihui 5:b8c02645e6af 62 *
yihui 5:b8c02645e6af 63 * LocalFileSystem local("local"); // Create the local filesystem under the name "local"
yihui 5:b8c02645e6af 64 *
yihui 5:b8c02645e6af 65 * int main() {
yihui 5:b8c02645e6af 66 * FILE *fp = fopen("/local/out.txt", "w"); // Open "out.txt" on the local file system for writing
yihui 5:b8c02645e6af 67 * fprintf(fp, "Hello World!");
yihui 5:b8c02645e6af 68 * fclose(fp);
yihui 5:b8c02645e6af 69 * remove("/local/out.txt"); // Removes the file "out.txt" from the local file system
yihui 5:b8c02645e6af 70 *
yihui 5:b8c02645e6af 71 * DIR *d = opendir("/local"); // Opens the root directory of the local file system
yihui 5:b8c02645e6af 72 * struct dirent *p;
yihui 5:b8c02645e6af 73 * while((p = readdir(d)) != NULL) { // Print the names of the files in the local file system
yihui 5:b8c02645e6af 74 * printf("%s\n", p->d_name); // to stdout.
yihui 5:b8c02645e6af 75 * }
yihui 5:b8c02645e6af 76 * closedir(d);
yihui 5:b8c02645e6af 77 * }
yihui 5:b8c02645e6af 78 * @endcode
yihui 5:b8c02645e6af 79 *
yihui 5:b8c02645e6af 80 * @note
yihui 5:b8c02645e6af 81 * If the microcontroller program makes an access to the local drive, it will be marked as "removed"
yihui 5:b8c02645e6af 82 * on the Host computer. This means it is no longer accessible from the Host Computer.
yihui 5:b8c02645e6af 83 *
yihui 5:b8c02645e6af 84 * The drive will only re-appear when the microcontroller program exists. Note that if the program does
yihui 5:b8c02645e6af 85 * not exit, you will need to hold down reset on the mbed Microcontroller to be able to see the drive again!
