Function Overview
This section describes the RL-FlashFS functions, which are grouped into the following categories:
- File I/O Routines perform file read and write operations.
- File Maintenance Routines perform file management operations.
- File Time Support Routines set time and date stamps.
- Flash Driver Routines perform read, write, and erase operations on Flash memory devices.
- FAT Driver Routines perform read, write, and erase operations on FAT media.
- MCI Driver Routines perform communication operations with a memory card in SD-Native mode.
- SPI Driver Routines perform communication operations with a memory card or SPI data Flash device.
- NAND Driver Routines perform communication operations with a NAND Flash device.
- IOC Interface Routines perform communication with all media devices that support FAT.
- System Routines to initialize the RL-FlashFS system or drive.
File I/O Routines
§ File I/O routines provide methods for reading and writing to files in a Flash file system. File I/O routines are not reentrant.
| Routine | Description |
| fclose | Closes the file stream. |
| feof | Reports whether the end of stream has been reached. |
| ferror | Reports whether there is an error in the file stream. |
| fflush | Flushes the file stream. |
| fgetc | Reads a character from the file stream. |
| fgets | Reads a string from the file stream. |
| fopen | Opens the file stream. |
| fprintf | Writes a formatted string to the file stream. |
| fputc | Writes a character to the file stream. |
| fputs | Writes a string to the file stream. |
| fread | Reads a number of bytes from the file stream. |
| fscanf | Reads a formatted string from the file stream. |
| fseek | Moves the file stream's in-file pointer to a new location. |
| ftell | Gets the current location of the stream's in-file pointer. |
| fwrite | Writes a number of bytes to the file stream. |
| rewind | Moves the file stream's in-file pointer to the beginning of the file. |
| ungetc | Stores a character into an input file stream. |
File Maintenance Routines
File maintenance routines perform file management operations. The routines are not reentrant.
| Routine | File System | Description |
| fanalyse | EFS | Checks the drive for fragmentation. |
| fcheck | EFS | Checks the consistency of the drive. |
| fdefrag | EFS | Defragments the drive. |
| fdelete | EFS, FAT | Deletes the specified file. |
| ffind | EFS, FAT | Performs a pattern-matching search for filenames. |
| fformat | EFS, FAT | Formats the drive. |
| ffree | EFS, FAT | Calculates the free space in the drive. |
| frename | EFS, FAT | Changes the name of the file. |
