fat16 --- FAT16 filesystem

fat16

File Allocation Table (FAT) is a computer file system architecture and a family of industry-standard file systems utilizing it. The FAT file system is a legacy file system which is simple and robust. It offers good performance even in light-weight implementations, but cannot deliver the same performance, reliability and scalability as some modern file systems. It is, however, supported for compatibility reasons by nearly all currently developed operating systems for personal computers and many mobile devices and embedded systems, and thus is a well-suited format for data exchange between computers and devices of almost any type and age from 1981 up to the present.

Example

Here is the pseudo-code for mounting a file system, performing file operations and unmounting the file system.

All function arguments are omitted in this example.

/* Mount the file system. This is normally done once when the
   application starts. */
fat16_init();
fat16_mount();

/* Perform file operations. */
fat16_file_open();
fat16_file_read();
fat16_file_close();

fat16_file_open();
fat16_file_write();
fat16_file_close();

/* Unmount the file system when it is no long needed. Normally when
   the application stops. */
fat16_unmount();
