Once created, the standard C file access functions are used to open, * read and write files. * * Example: * > #include "mbed.h" * > * > LocalFileSystem local("local"); // Create the local filesystem under the name "local" * > * > int main() { * > FILE *fp = fopen("/local/out.txt", "w"); // Open "out.txt" on the local file system for writing * > fprintf(fp, "Hello World!"); * > fclose(fp); * > remove("/local/out.txt"); // Removes the file "out.txt" from the local file system * > * > DIR *d = opendir("/local"); // Opens the root directory of the local file system * > struct dirent *p; * > while((p = readdir(d)) != NULL) { // Print the names of the files in the local file system * > printf("%s\n", p->d_name); // to stdout. * > } * > closedir(d); * > } * * Implementation Notes: * If the microcontroller program makes an access to the local drive, it will be marked as "removed" * on the Host computer. This means it is no longer accessible from the Host Computer. * * The drive will only re-appear when the microcontroller program exists. Note that if the program does * not exit, you will need to hold down reset on the mbed Microcontroller to be able to see the drive again! */ class LocalFileSystem : public FileSystemLike { public: LocalFileSystem(const char* n) : FileSystemLike(n) { } virtual FileHandle *open(const char* name, int flags); virtual int remove(const char *filename); virtual DirHandle *opendir(const char *name); }; } // namespace mbed #endif
