Once created, the standard C file access functions are used to open, 00043 * read and write files. 00044 * 00045 * Example: 00046 * > #include "mbed.h" 00047 * > 00048 * > LocalFileSystem local("local"); // Create the local filesystem under the name "local" 00049 * > 00050 * > int main() { 00051 * > FILE *fp = fopen("/local/out.txt", "w"); // Open "out.txt" on the local file system for writing 00052 * > fprintf(fp, "Hello World!"); 00053 * > fclose(fp); 00054 * > remove("/local/out.txt"); // Removes the file "out.txt" from the local file system 00055 * > 00056 * > DIR *d = opendir("/local"); // Opens the root directory of the local file system 00057 * > struct dirent *p; 00058 * > while((p = readdir(d)) != NULL) { // Print the names of the files in the local file system 00059 * > printf("%s\n", p->d_name); // to stdout. 00060 * > } 00061 * > closedir(d); 00062 * > } 00063 * 00064 * Implementation Notes: 00065 * If the microcontroller program makes an access to the local drive, it will be marked as "removed" 00066 * on the Host computer. This means it is no longer accessible from the Host Computer. 00067 * 00068 * The drive will only re-appear when the microcontroller program exists. Note that if the program does 00069 * not exit, you will need to hold down reset on the mbed Microcontroller to be able to see the drive again! 00070 */ 00071 class LocalFileSystem : public FileSystemLike { 00072 00073 public: 00074 00075 LocalFileSystem(const char* n) : FileSystemLike(n) { 00076 00077 } 00078 00079 virtual FileHandle *open(const char* name, int flags); 00080 virtual int remove(const char *filename); 00081 virtual DirHandle *opendir(const char *name); 00082 }; 00083 00084 } // namespace mbed 00085 00086 #endif
